Thank you very much for sharing this info. I'm sorry, I've tried all the solutions, unfortunately, my problem continues.. I have 3 PCs. PC1 is our server PC with a practice management program. I have mapped the drivers of the 2 workstation PCs to the server PC for full access of the program read and write. I have turned off LSO and network speed has improved but only when one workstation is on at a time, when both workstations are on, network speed is slow.
Does anyone know what else could be the issue? Have I mapped the drivers wrong? Do I need to reset my modem? Wow, changed settings in the middle of a copying files.
Estimated time started at over a day and dropped to mater of about 20 minutes. Worked great make sure not to forget the reboot. Tried looking for this option on my windows 8 machine, and don't see the options listed under the advanced tab when I double click on my network adapter, could it be stashed somewhere else? Called something else? Any ideas? Thank you sooooo much. Now I just need that fast speed out of my wifi. Is there a trick to that too?
It worked for me although in my case the v2 options were already set to disabled and the non-v2 option "large send offload IPv4 " was enabled. I don't see Large Send Offload. HELP my speed is only a few kbps. I have something different - "Task Offload" in my Atheros L1 Gigabit card, Should this be done on both computers or just the sending one?
Assumed both. Thank you so very much. Its working as if my network is on Steroids. I have a NAS connected to my network and only the top folder would connect and the rest of the folders would take up to 15 seconds to give me the log-in window, now, it doesn't even take a second.
I appreciate you writing this up! It appears to be the answer to my problems as well. The only question is, I have workstation 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 This issue seems to be running rampat among Win7 users trying to network to non-Win7 machines.
The following link has also been covering this topic in detail. Check the troubleshooting steps I've taken towards the bottom of the thread. Win7 and ServerR2 are essentially the same version of Windows And most of the posts above yours discuss Windows to Windows slowness, including references to the "other" thread suggestions that don't work for us.
So unless you can add "Helpful" commentary? I did try ALL of the recommendations. No significant help, what so ever. What did work was disabling Windows Search by disabling the Windows Search indexing service.
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. Robert Seward- Sr.

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. For example, your newest toy may support WiFi 6 , but the rest of your network consists of WiFi 4 and 5 devices. Likewise, Ethernet adapters that support 10GBps, 1 Gbps, Mbps and even less on old hardware may all be mixed together.
In these cases the lowest common denominator will limit data transfer speeds, causing an overall slow network. But there are situations where the adapter itself could be misconfigured. The network interface card in your computer, whether Ethernet or WiFi, will also get driver updates from time to time. In this case a network interface device.
If there are bugs in the driver or developers figure out better ways to manage network traffic, a new driver will bring those improvements to your device. Network interface hardware also benefits from firmware updates and fixes.
Usually the best place to look for these types of updates are on your motherboard or computer manufacturer site. Firmware is the hard-coded internal code that operates the network hardware on the most basic level. New firmware updates are used to patch bugs, improve stability and even add new features to old hardware. All of these might improve network performance.
Our networks now have more than just traditional computers on them. Some of these devices might cause congestion or other network performance issues. This is one of the reasons you should avoid buying off-brand network devices. Your computer and your router both support a specific network speed. Yet, when you copy a file over the network, you get nowhere near peak performance.
Still, the problem might very well be your Ethernet cable. While Ethernet cables may all look pretty much the same, different categories of cable are made differently. This has a big effect on their performance. They have different levels of shielding, different numbers of cable twists and so on. The help desk software for IT.
