YES or NO.. Solution 2: Disabling Auto tuning. I think this will have more effect than the solution above. Disabling auto tuning in Windows 7 will help much on DNS lookup and network discovery and will eventually improve the data transfer speed across the network. You must be logged in to post a comment.

Microsoft themselves have instructions on how to set up a cable-to-cable connection.
After that is brought to work, I'll try with some of my routers - not before. What tells me that it is part of the OS is that I can not drag numerous folders to the desktop and the system be able to handle the copying. I'm not a software engineer, but logic tells me that if I see this problem at this level, then it is in the system design. As a computer consultant for many years now, I've copied large data folders and files through every OS that is commonly used.
I have never seen an OS choke before the way Win 7 is doing when trying to move several folders with large amounts of data at once over from an external source. But: Is this the same when copying between 2 Windows 7 PCs? Is there a difference when connected through Homegroup or Workgroup? An IT friend of mine referred me to this thread as I'm having the same issue as others. Listed below are the specs of the machines and network. From the Win7 machine, I am unable to copy large files across the network to the XP box.
I've tried moving smaller files and they seem to copy across the network without issue. Unfortunately the size of the file causing the issue is not consistent each time and therefore I haven't been able to pinpoint a size threshold when the copy fails. For instance, the test file I have been using is a folder that consists of files for a total of 6. When I try to copy the entire 6. Make sure you are connected to the network and try again. The error message is produced once copying of the first large file is attempted.
I have been using the same test file for which is a folder consisting of files for a total of 6. Below is a list of the troubleshooting items I've completed so far. Replace Cat5e cables on Win7 and XP boxes - no improvement. Disconnect all cables from switch except for Win7 and XP — no improvement. Changed ports on switch for both Win7 and XP — no improvement. Turn off antivirus on both machines — no improvement. Plug only Win7 and XP box into Actiontec router, taking switch out of equation — no improvement.
Force full duplex, speed on both machines — no improvement. Disable auto tuning and receive side scaling on Win7 box — no improvement. Turn off Remote Differential Compression on Win7 box — no improvement. Install 8gb new memory, certified compatible; ran MemTest on each stick and again with all 8gbs installed and no errors reported — no improvement. Updated to latest MB Bios — no improvement. Ran copy command in DOS prompt — no improvement. Unchecked IPv6 in network properties — no improvement.
Turned off all power save options related to NIC on both machines — no improvement. Formatted both Win7 and XP and did clean reinstall of operating systems and bare essential drivers — no improvement. Uninstalled all Win7 critical updates — no improvement. Slightly better performance but still nowhere near speed copying in the opposite direction. Both machines in normal operating mode: Same issue as stated above and only small files are copied.
I've searched the internet and found plenty of posts from other Win7 users being unable to copy large files to XP across a network, but haven't found a real solution or explanation of what is causing the problem. I've also read somewhere the problem may be an issue in networking a bit and bit operating system together.
I'm l ooking forward to Microsoft finally admitting there is an issue and offering a solution!!!! Was anyone around when OS 7 was born out at Apple? After having gone through and survived that evolution, which almost did Apple in , I'm cynical enough to not try everything MannyL did, and wouldn't even begin to try to figure out what is wrong with the OS.
There isn't one team at Redmond that thoroughly understands the workings of the whole OS across the board under the hood at every level. How can any of us even begin to fathom why Windows 7 is doing this?
What is obvious to me is that it is doing this when I have a 64Bit machine with Windows 7 and using an external drive over USB2. This is a problem with the system, not unlike the wrong direction taken by Apple at one time. When Microsoft gets its priorities right again, and gives the market a lean and mean OS that can optimise the power of hardware we have now, not use it as a crutch for its media center and DRM priorities, they will be able to resolve this problem.
Until then, it is a matter of getting them to address this issue publicly. But this sure reminds me of the old OS 7 days on a Mac. And we haven't even begun to address CPU chipsets. It could be at that point where these problems begin. One person I know using AMD Dual Core is not seeing the copying issue as badly as we have, but still unusual responses when trying to copy multiple folders at once.
Vegan you are not addressing the issues we are talking about, instead diluting the essence of our discussion with off the cuff remarks that have nothing to do with reality or this problem. But here is a thread with a whole 9 pages of similiar complaints and they have nailed down the OS as I have as the culprit.
Not to mention the misdirection of MS. I see you've done a thorough job in locating the problem. I've tried most of what you did apart from reinstalling os. And I don't use a router. Firewall is disabled since these machines are not going to be on the internet or use wireless. If I choose to show Details from the copy-dialog it's obvious that the speed goes up and down a lot.
This suggests it's some kind of software-issue maybe with the packets not being received in the right order. Then I found this post and tried most of it without luck:. So: what's left to do? Shouldn't it be possible to have one or more skilled persons at Microsoft to read through this thread and look into it? It's not fair we have to do this amount of job just to get things to work the way they're supposed to. Installed Windows Resource Kit for Server www.
Since the copy was performed across the wireless network, transfer speeds were a dismal 2. Adjusted the following settings on Win7 box SpeedGuide. I left all other settings unchanged. I needed to confirm which parameter adjustment fixed the problem, so one-by-one I changed each of the above parameters in step 28 back to the original setting Strangely enough, there was no impact on the file copying from Win7 to the XP box!
It still worked!!! I continued to try copying the large files and it seemed as though the transfer speed decreased with each attempt. I then changed all of the TCP Global Parameter settings back to the original settings basically the starting point of step This time only the first file in the folder of files 8kb copied and nothing else!! Apparently Windows 7 can learn, adapt and outsmart traditional troubleshooting techniques and can adjust on the fly to continue to screw with its end users.
How can making these changes after step 28 result in what seems to be a closed case, quickly turn into the same issue again without any other setting adjustments?!?!?!
I want to thank you so much for sharing your experiences. Went over to microsoft-site and saw all the Answer-forums, where a lot of people asked and got answers, but no solutions. When looking at the age of this thread it's becomes evident, that we have to solve this ourselves, so thank you again. Though it didn't help me, from what I understand from the Speedguide description, the Heuristics is where you turn off the "intelligent" Windows behavior.
Now I'll have to admit, that though develloping software for 30 years and using network a lot in big companies, I'm not an expert in how a network works. I guess, that when the two boxes have negotiated a speed, this should be the same both ways. If I can send at close to 1Gbps it should be the same the other way, right? Like you I've only tried settings on the Windows 7 PC.
But wouldn't it be logical, if the older equipment like sends in an older format, which the newer equipment understands and then when the newer equipment tries to send in a newer format, that the old equipment doesn't understand, things go wrong?
I'm thinking about trying to fiddle with the XP box - have some work to do first, so will get back. Hello Everyone Of course, I also had the issues you all have described, and I have tried some things as well to try to get over this annoying file copy issue. One thing that got me some significant inprovement was to modify the 'Interrupt Moderation Rate' for the adapter from Adaptive to High. After changig the value to High, I saw a marked improvement, but it still wasn'tas good as I had hoped.
I was about to give up when my coworker came over and told me to try the next thing, which seemed so trivial, I scoffed at him As soon as I did that.. I had all my file copy speed back. The link speed auto negotioated to the same speed and duplex I had forced, but auto negotiating must do some more tuning than that. I hope this helps some of you. I'm sure it won't work for everyone, as this problem seems to have many facets to it. USB Drive copy slow??? Just Strange. Anyway, good luck to everyone - and I admit..
I stopped reading at about post 80, so I hope this hasn't already been put out there. Since it works one way, it must be related to wrong packet sizes, missing acknowledgement from the receiver or the like. But frankly: I'll have to give up on this one and get back to normal life.
Will check back from time to time so every effort is appreciated. I've been following this thread for a long time, and I have the same problem as most people have. I've been struggling with this problem since Win7, day one, and after playing with some NIC settings I managed to get this performance.
In the beginning it was about the half of what I get now. The big mystery is when I use my Win7 machine you can see that the difference in copy speed is very strange!!!
I think this is the biggest bug in Win7 - ever. The answers from MS are quite silly. Hi everybody. I tried it, and most of the tweaks you else have to key in manually can be made by just pressing a button. Works for both XP and Windows 7. And it gives you the opportunity of choosing between Windows default, Optimal and Custom.
Found it very intuitive too. No installation required and all free. You could wish the same people would've made an operating system this way.
Let me assure you that I have no interests in Speedguide. One for the network adapter, and the one in Netsh int tcp global. Off course I've tried any combination of these without luck, but just out of curiousity: what's the difference?
With Vista and Windows 7 they sold out not only their user base but also the hard won advancements in hardware efficiency by creating an operating system that catered to the corporate pressure of insuring maximum protection for them with digital rights management built as a core priority.
We need to complain loudly and often that they will lose their market that clings to XP someday to Debian. And the market that clings to XP is the professional user base that wants nothing to do with animations and swirlysquirley cutesy nonsense taking up valuable cpu resources.
We want nothing to do with an operating system that tries to control the user at the cost of efficiency and speed. When you can not copy two large folders of files to a desktop at the same time when you can with earlier systems and all their competitors, that says more than any tweeking will ever cure in this case.
I have several Windows 7x64 SP1 machines that are super slow browsing my network to my Windows server. They are also super slow transferring files. Here's what is odd. Box 1 had the problem immediately after installing SP1. I updated drivers and reset the NIC numerous times. It would work fine for maybe 30 seconds after resetting the NIC and then go slow again.
I was finally messing around doing pings which seemed fine and used the - L switch and some byte packets and it suddenly started working ok. After a reboot box 1 is back to the network transfer in the low KB range.
Transfers to a USB flash drive seem fine. Box 2 did the same thing after installing SP1. I messed with it for hours and finally uninstalled SP1 and everything was fine again. Box 3 I did a clean install with a Win7x64 SP1 disk. Same super slow unusable.
I came back to it a week later and it popped up the IE9 install that I had started the week before from the W2K3 box. After the IE9 install it's working fine.
This is clearly a Win7 issue. I've got several others here that seem ok but I'm not about to install SP1 on them at this point. After several months of dealing with not being able to backup over a network drive, today I finally solved this problem by changing the adapter speed. Mine was set to Full, and first I changed it to 10Full and was able to finally copy a large file over to my XP file server.
I then changed it to Half and was able to copy a 1. I have several clients that have had these issues and most of which are wifi connections. I had one that none of the other solutions could resolve, so I went back to basics.
OK I am going to ask for the following information from each reader who has issues of this thread. I have been using networks since the days of coaxial networks so I have the experience, but I need details galore to figure out the problems. You have it right. Netgear switch is unmanaged and it does not have the ability to act as a DHCP. I haven't changed anything related to the network hardware or settings since my last troubleshooting post.
You'd think after a year and a half, MS would finally fess up and offer a fix. I do not like primitive boxes that cannot be managed, useless in my opinion when problems surface.
If you can afford it, Linksys is a better brand. The wireless boxes can be DHCP or it can be turned off. They are very good and I like them. You can also disable the wireless if you want, or simply isolate it from the LAN to make it a hotspot. Unfortunately I cannot help with your provider;s gear. Works like a charm.
Now if all of the gear is attached to the netgear box and its slow, then there is a real bad problem. Likely the netgear box is reducing the network speed down. We move movies of GB each from one drive on the network to another. The drives are on XP machines. The files fly. The copy grinds to a halt! You already irritated most of Win7 users with the idiotic "AERO" problems with unreadable text on white background "This is by design".
Has service pack 1 fixed things for anyone? I think it has many of the hotfixes that have come out. Alternative possible to verified with you if there are alot of subfolders in the parent folders?
If so i would suggest you to use robocopy. I documented my individual issues thouroughly. One thing I noticed on my own system, a laptop, was that IF I was on batteries the processor speed slowed to a crawl as did file transfers. Plugged it in and speed improved. Not great, no where near ftp speeds, but quite a bit better.
One other note, have you noticed that some backup vendors now support ftp as their file transfer protocol? MS needs to address this very significant problem. It's turning windows 7 into a second rate OS. I to have been searching for the answer to this question for 10 months I have two boxes with wired connections to the same router.
Both mounting a Linux drive using Samba. From my Vista box, my build copy of about small files takes 30 seconds. From Window 7 it takes 53 minutes. Given this setup, it is clearly not the router or anything behind it. Now I am back to the original driver that came in the original package. This is an issue with Microsoft 7, there are folks here that agree with this assessment. The only one who disagrees in Microsoft. I have finally bought an Apple. I am working thru the issues, but it copies the same files in 17 seconds.
Listen to me I know it's a pain, but the alternative is spending 10 months trying to copy files on a connection traveling 3 feet in under an hour I believe it would be faster for me to manually type the 1's and 0's using visual inspection than to use Windows 7 to copy them.
Yada yada yada. The Macintosh grass is not greener, it's just spraypaint. You'll have other, different problems. All computers have them. I'm not making light of your problems, but there are Windows 7 systems that are and have always been quick to copy files across a network.
Noel, you can say that, but I spend time supporting different systems. When I have the same installs and work across XP, Vista and Windows 7 to do on different machines, I end up sickened at the lack of speed, efficiency and the errors encountered with Windows 7.
I never thought anything could be worse than Vista initially, and on the surface Windows 7 seems an improvement, but under the hood it is a Pandora's box. Everything takes longer and encounters more problems if not failures that are unlikely to be easily resolved under Windows 7.
I support Macs as well for almost 15 years, and that is not an oasis that the MS users could take to. MS is commiting sucide. Where can they go from here? Backwards would be a start! I want to qualify first by saying I have read all of the posts to date and I hope you keep this thread going until we can arrive at a solution! For anyone interested, I just want to share a little of my experience with this problem I have 20 or more customers with multiple networks different hardware, different locations, different environments - totally disconnected from each other that have this problem.
I worked for a month or more with Microsoft on this issue but still did not find an answer. We did everything mentioned so far and I submitted netmon logs multiple times, had the issue elevated, and finally the second level supervisor dood told me the networking was working correctly and closed the call. I proved to them that the weaker XP machine was at least 3X faster copying files to and from a shared folder on a server. Even their guys don't know "why" but I've shown them.
I honestly believe that this is occurring for the same reason the file copies are so slow and if I can solve one problem, I will have solved both. It seems to be a "networking problem under current versions of windows". When these strange errors occur, there is always a MRXSMB delayed write type error in the log - directly corresponding to the time of the application problem.
I know about OPLocks and have had to manipulate the settings to fix the errors in some cases. However, it slows the network down quite a bit so it's a bad solution. Copying files in a reasonable time across the network to me is like oxygen to a boxer. Without it, he's screwed. He may have nice gloves, nice shorts, be in great shape, but it simply doesn't matter, with no oxygen he's going to get his head pounded in. I guess other folks only use one computer, but for me this is a situation that simply can't exist.
Do you think I really wanted to buy a Mac? I'd rather bait a crocodile with my Johnson than to make this move, but I cannot exist with a simple project build that takes 53 minutes. That may seem trivial to you, and you can downplay the Mac all you want, but you're not feeling me This is an interesting thread and frustrating problem for sure.
Remarkably different, but with the same issues. That tells me this is an OS and not an infrastructure problem, in most cases. I've been in IT for 15 years so I've seen a lot of the ethernet issues described by others here such as duplex mismatch, etc. When Vista came, out I had similar issues. I had a Linksys router at home and Vista just would not work with it. I finally traced the issue to RSS or receive-side scaling.
Disabling that resolved the issue. Newer routers seem to be able to tolerate that feature as I now have a D-Link Just this week I deployed a Dell Optiplex for a user and this problem again reared its ugly head. Force 10 S50N switches not cheap! Traditionally for this to work you need both NICs, client and server, to have this enabled for it to work. You also need to be able to enable this on your switch. Normally in most office environments because you have a mix of traffic from Wifi, printers, clients, etc to servers, LAN side traffic can't be set to jumbo frames.
There are differing opinions regarding this, but that is what I have been able to determine over the years. So as you can see this is good hardware and very fast switches. Everything is set for 1Gbps, auto-negotiation as recommended by VMware. Other services such as Exchange , SQL, etc are running on this infrastructure without issue, although I do occasionally here people complain about things being slow.
Checking network and SAN performance logs never display a cause. After all of this, I think the one common thing I'm seeing here is a combination of network driver settings and the Receive-Side Scaling and Autotuning issues. The problem is there are so many potential settings with Intel Gb NICs it is hard to know what is making the issue better or worse. That didn't work in my case. When this issue explorer copy process hangs when copying TO a server share first occurred on this particular PC, I made sure to download all the latest Dell and Intel drivers, chipset, NIC, etc.
After those were up to date, the problem remained. Then I started messing around with disabling IPv6 on the client I have left it disabled. It was already disabled on the server.
