I have Windows 10 21H2 (updated about 1 week ago). Problem existed before updating to this version.
1 or 2 gig mp4 file transfers at gigbit speeds from windows to either of my NAS boxes.
If I select a large number of jpg's network speed may go from 2 MB/s then pauses, drops to 1.34 MB/s (or something like that) then pauses, then may jump back up to 2.5 MB/s then drops to 0, then goes up to 500 Kb/s and so on time remaining for 200 files at 920 MB says 21 minutes.
Sometimes it will start out pretty fast like 22 Mb/s then quickly drops to nothing or may jump up to 35 MB/s or even 70 MB/s then drops to 1.81 MB/s. Sometimes it sits for a minute reading 0kbs.
originally I thought this was a problem with the settings on the NAS boxes, but after posting on forums for those devices (and getting nowhere) I recently pulled out one of my old laptops with windows 7 on it. hooked it up to a wired gigabit connection and disabled wireless. I then transferred a pile of jpeg files from it to the NAS and the speed was the same as for transferring mp4 files. so the issue seems to be with windows 10.
also transferring files over 2.4ghz WIFI with CX file explorer (from my phone) is WAY faster, fast enough that I stopped using USB to connect to the computer as windows would slow the process down to a crawl.
Things I have tried:
every forum on the internets recommendation for changing settings on my network card (nothing makes a difference).
various versions of smb, and NFS.
every suggestion to change settings on the NAS boxes.
so many things I cannot begin to list them here so don't be surprised if you offer a suggestion and I say "tried that didn't work".
I worked in IT for 22 years and had to copy and move files all over the place on peoples networks and while small files do copy slower. I have never seen copying this slow, also it only occurs copying to my NAS boxes, not to a USB drive, not to another network computer, and not when copying from my NAS boxes. Heck copying to an old SD card is faster.
I just tried it with my wifes laptop wired connection (100Mbps) and windows 10 it was slow but not near as slow as my computer.
