Windows 10: Incredibly slow file transfer
I have the same issue reported here by others.
I have a gigabit intranet with 3 PC (1x win 7 + 2x win 10) and I need to copy huge amounts of data between them (>5 TB).
Although I see the same problems as almost everyone else here, i.e. my transfer rates are never higher than 25MB/s when copying data from one PC to the other using the windows copy process, I did carry out some test using the following software: Downloads | Totusoft
The results are impressive!!! Testing the transfer of files of 500 MB I get up to 800+ MB/s transfer (in both direction and between all PCs), which is what I would expect from my pc/network configuration.
So, as I see it, the problem does not lie in the hardware, but in some windows stuff. And I have it for Win7toWin10 (and vice versa) as well between two Win10 PCs.
Could you please check the transfers on your PCs using the same software and report, what the results are?
Some new ideas about why this happens?
This issue is from when they made windows xp, Microsoft did think lets make a bandwidth reservation, what is a registry setting.
If you have 1Gb network throughput, what is 100% there would be 15% till 20% reserved for Voip, error and other stuff (this is agreed over the whole world).
So if I have large data transfers from my windows 10 computer to my NAS (openmediavault, unix/ Linux, which don't care if I use my hardware full potential) and visa versa, I will get a transfer speed of around the 84MB a 86MB, which is around 84% usage of my 1Gb network (16% is for Voip and stuff).
If I do the same thing between two windows machines is the datatransfer only 30MB max.
Microsoft thought lets reserve 60% of the bandwidth and use only 40%, now if you have 1Gb network (100%) and only use 40% which is to be handled as 100%, minus the 15% till20% reserved for voip and error, you will get 25MB to 30MB datatransfer. then it should be the case that if we have 2 datatransfers from one machine to 2 different machines, the transferrate should be both around the 25MB a 30MB, but this is in best case.
Within windows7 can this problem be resolved, by Disable Bandwidth Limit...
I used for this GPEDIT.msc and then within computer Configuration, Administrative Templates, Network, QoS Packet Scheduler.
Double-click on Limit reservable bandwidth.
And disable it.
IMPORTAND NOTE: this has to be done on all windows machines. and watch out with the use of Gpedit.msc
For windows 10 I have to vind out for myself if this works.
I hope this was helpful enough..
I got the transfer speed back by adding the application c:\windows\explorer.exe to Windows Defender exclusions, perhaps not the best solution but worked well for me.
I have found a fix
I had found a fix which i would like to share. It is in the post which i made. Links are as given.

Worked for me! Good find. USB3.0 memory stick now transferring at a decent transfer rate instead of keep stopping and starting.
I also have been encountering this issue. It also works for my USB 2.0. Thks for replying
So I just took part in the Windows 10 Insider Preview a couple of days ago, and I have to say, Windows 10 is a great step up from Windows 8, they did an excellent job so far. There's just one problem: File Explorer is extremely hard to use. Not only...
I installed Windows 10 last week as an upgrade from Windows 7, and the internet part is working good. But something with the file explorer didn't work. The Document, Pictures, Music, and Video files are still there, but the thumbnails load slowly,...
I am using Win10 10240. I have a problem copying a large number of big files. The setup is a bit tortuous.
The source is an old WD Cloud NAS on ethernet via my ethernet connected router.
The destination is an external hard drive on USB3.0
