Other notes: Explorer copies are slowest; Robocopy is pretty fast - faster if you make use of the multi-threading options; Richcopy blazes, but with the caveat it often misses files because they are in use -- so watch your logs when copying important folders. Thank you guys so much. I have 5 pc's networked in the house with various media files on each.
Everything worked fine except for one hardwired pc. From the "advanced" tab, I disabled "energy star" option. Network copies went from MBps to MBps. This was a Marvell NIC. On a 2nd computer, with a Realtek NIC, the "green ethernet" and "energy efficient ethernet" that needed to be disabled. On a 3rd, with an Intel NIC, it was "energy efficient ethernet", "reduce link speed during standby" and "reduce link speed during system idle".
Thanks very much John, this worked perfectly. I had been struggling for a week with this and tried most of the other solutions proposed before I found your post.
This fixed it right away! I've been struggling with this for nearly a week. Found John Elion's fix, ran it and bingo! All's good. Did these power management things too - just to really hammer it home and now all is sweetness and light. It's not as if file copy were a rarely used or trivial function. I'm baffled 'ere. Anyway, my purpose in writing is really just to thank all you people who put the effort in end eventually did the vendors' job for them. This is the most frustrating Win7 problem with an answer that has eluded almost every forum on the internet regarding its solution.
The problem for everyone is the same Go To Start Then restart your computer test out your fast speeds Then curse every hack that told you to download a "file transfer manager" to fix such a basic windows function. Please try the examples given but if you don't have the right switch then it won't matter what you do at the OS. Internet speeds were fine but copying files from one PC to another via shared folders was ridiculously slow.
What finally worked for me was enabling jumbo frames in the advanced network settings of my router. Desktop to desktop over the wired connection is too fast to measure. Just thought I'd pass it on as I've been fighting with this issue for quite a while.
Another update. I disabled the two settings for the wired network card on the x64 desktop that others have mentioned:. I also disabled jumbo frames on the router after this and am still getting good speed, so that seems to be the fix that did it for me. Thanks to all for posting here. If your internal or external networks do not require IPv6 protocol, better remove it under network connection properties. Keeping IPv6 in your computer sometimes slows down network by trying to register IPv6 addresses, or trying to get IPv6 address, or trying to resolve IPv6.
This thread needs a bump to get it further up in Google's search results. I've been going crazy for a day on this, mostly finding rants, not solutions. No joy. I'd also tried booting into safe mode ie, no sense in blaming Adobe, Norton, etc! I'm pretty sure that a lot of other people aren't experiencing this problem and aren't narrowing in on the 'network' part of this issue soon enough. Some of the commonly proposed fixes disabling thumbnails, etc probably do improve the results for some people under some scenarios, but only because they reduce the amount of network traffic I tried many of the proposed solutions here including exiting home group and disabling the Large send loadoff but nothing worked.
I happened to open my firefox on the receiving computer the vista computer that I am copying the files to and when it was downloading some firefox update from the internet, the local file transfer rate went skyrocketing simultaneously.
I thought, "that's strange. I thought the competing bandwidth would slow down the transfer even more", but the opposite was true. So I did a little test, I opened firefox, started watching some youtube vidoes on the receiving computer and at the same time transferred large files over.
Lo and behold, the problem solved. That's 20x faster. How can this be? Perhaps someone with more tech experience can look into this and find some explanation for it. Because it's the last thing I expected. I just wanted more speed to pass all my files from my old system XP to my new one windows 7 , my speed was 2. I've had this issue of "slow erratic file copy" over the network for a couple of months, still trying to resolve. Symptons: Stuck on "calculating" screen The only workaround that seems to work is by temporarily disabling the internet connection on the PC where files are being pulled from.
Tried this on all 4 PC's running windows 8 on my network. Weird but it works for me. Still would like to know why this happens or what is causing it. Just to double-check, I re-enabled the above commands except 'autotuninglevel' and rebooted, tested again and found myself back on the slow transfer speeds I've since disabled them again and slow transfer are fixed.
What the problem was, is I have Gigabit exclusively internally and two of my computers did NOT have that enabled. Taking your advice first, I disabled on the one PC that is was and my whole intranet ground to a halt almost.

However I have major performance issues with network file transfer for backup. My home server runs WinXP Pro 32bit. Facts : Network : All uses ethernet cables, only.
NO Wifi, at all. Linksys router. Use SyncToy to copy files - no improvement 8. Googled for hours on end and attempted x number of other suggested fixes - no improvement Questions: 1.
Does anyone know if this is a known problem for: Nvidia nForce drivers Windows 7 Ultimate 64 bit Other 2. Are there a fix underways? Does anyone have any suggestions for fixes I might try or an actual solution? Last fact: Im desperate and frustrated :S. Kind Regards Christian Mikkelsen. Saturday, October 24, PM. Try RichCopy. This step can help you determine whether the problem is caused by the DFS path. If it is still slow when you use the UNC path, see slow performance when you copy a single file, a folder, or multiple files.
If the issue is still not resolved, see server side troubleshooting. If you compare the copying time for a folder that contains multiple files with the copying time for a file of the same size, copying the folder will always require more time. This behavior is expected. The more files that are in the folder, the slower the file-copying process. Delete the third-part network provider from client computer. The default options are as follows. Any other provider can be considered as a third party.
Is there any way for a Group Policy to be made for this so that I don't have to visit workstations? The Offload setting fixed my Windows copy speed! Funny though, if you use a different copy manager like TeraCopy, speed was pretty good. This worked "like a charm Quote from "Santoxthanksyou" above "! Thank you I followed your steps exactly for both computers the third suggestion, the one that worked, the "LOS" option -- didn't even have to re-boot but will do it anyway before this put the transfer speed "on Steroids Quote from "Brian" above.
Thanks for posting this. I had to both disable LSO and enable jumbo frames to get the performance improvement, but importing a CD now only takes a couple of minutes. I get to step 5 and instead there is no list of options under the advanced tab Just a button "nvidia Ethernet configuration" which when I open it lists some options but not the LSO option I can't seem to fix my problem.
I tried all 3 options but the speed just around k. I tried to get into the network adapter setting and find the "Link Speed" is set to "mb Full Duplex", so I set to "1. Some time ago I experienced a slow connection when transferring large files. After I disabled large send offload on my networkcard killer e gigabit ethernet controller ndis 6. Since yesterday I have a slow connection again. I didn't install something new and LSO is still disabled. Any ideas how I can fix this? Thanks in advance,.
Thank you for the info. I really helped was struggling with slow lan for 4 days nothing helped but these changes made wonders.. Can't believe this. Saved the day for me. Thanks a lot for sharing the solution. I was transferring data over LAN between 2 laptops one of which is Windows 7 and another is Windows 8. I tried ll your suggestions to increase speed. I just wanted to chime in and express my gratitude for this solution.
Ah finally i found a solution! Starts of at or so. I tried these without much luck. Turned on autonegotiation and bingo. I think I might owe you something huge for this, but have nothing to offer. This brings about the end of a very long-term frustration. Many thanks for this post.
You deserve an award or something. Thank you very much. It was one older computer on our network that was slowing down other resources. After disabling LSO on that station it has helped all around. I did the opposite. I enabled Jumbo Packets, the largest size. That fixed the problem. However, my case is special. I am downloading over a university campus LAN. If you have that service running, check this article on how to remove it.
Thank you, thank you and thank you. Any ideas how to fix slow speed transfer over VPN? I know to some degree the speed is reliant on the VPN provider. Waiting anywhere between 12hours and 18 hours is way to slow for a 20gig file. I am getting speeds of kb or less. Very slow. Check this article. It has quite a few suggestions on how to fix slow VPN speed.
For years I struggled with slow speeds thinking that it supposed to be like that. Thank's heaps. It might help you steer into right direction. For example, the answer has the following information about "Jumbo Frame" :. If users enable both of them, the driver automatically chooses Jumbo Packet. Now both directions work. What a stupid feature. Thanks so much!
The large send offload was my problem too transferring files between Windows 8 computers, only in one direction wireless to wired. Now I'm maxing out my wifi again. My file transfer speed over an ethernet cable was awfully slow. About 25kbps. I did 'netsh' change and it boosted up to 8mbps.
Then I advanced and did the 'ipv4 and ipv6' changes on both of my laptops. But as soon as I opened another folder in the file explorer of my sending laptop, the speed dropped to around 46mbps, and the laptop started lagging and hanging.
When I let things get stable, everything was back to normal. After everything, I reverted the settings everywhere, to avoid falling prey to anything fishy, should a problem decide to approach me in the future. Thanks for this article, though, I wanted the transfer speed to be above mb but it became better after following the steps provided in this article.
Well anyhow thank you VERY much! This only started two weeks ago after having good speeds for years. Thank you so much. I would not have found this without help. I searched for increasing speed day by day, but i lost This is my email , someone can help me by sending me a reply to this e-mail, thanks!
Amazing and thank you! And curses to the buffoons who invented it, who improperly implemented it, and who decided to enable it by default.
It doesn't work for me I wish to transfer GB files from Windows 7 to Windows I have tried the above-mentioned solutions.. Is there anyone have some good ideas? Thank you so much for this! I can't believe your first fix worked for me. My connection was literally taking 30 minutes per photo. Still relevant info - You're a superstar! To increase transfer speed. Thank you for the suggestion. We have just upgraded to win 10s and were experiencing slow transfer speeds from our workstation to poor Synology.
I was blaming Synology, but of course - in our case the solution was to disable the Windows Defender. The issue was NOT related to anything networking. Dear Sir, My self a computer hardware engineer.
I have same query regarding network issues at my client's office. My client wholesale dealer of medicine. For day to day business operations he is running a billing software. This software Visual Studio Foxpro is installed in more than 3 to 4 computer including server computer. The software runs with efficient speed in server computer but the problem arises when it is operated in other computer. It lacks sufficient network and speed.
Therefore, kindly suggest same remedial measures regarding above stated query. Thanking You. This worked for me media server settings was causing my video to lag and even drop occasionally. After disabling the LSO, not only did my video lag stop, but the audio quality greatly improved. Plex has been driving me mad keep buffering.
It was fine, then it started doing it, then it decided sometimes to do it, and then not to other times. Even an image slideshow would sometimes buffer when it was in a bad mood. Although disabling the LSO appears to have fixed the basic issue, I have since discovered that it is possible a large or corrupted cache for the Plex app can also lead to issues. I've watched several movies with no issues since applying the LSO fix up until then it was a big problem. All of a sudden last night - in the last 5 minutes of a film - buffering started again.
It was also immediately apparent when I tried it on another movie to try and figure out what was happening. If you do not see your language, it is because a hotfix is not available for that language.
