Strange performance issue with FileZilla lagging/freezing/slow performance.
Posted: 2019-12-22 00:42
Hi.
I've done a fresh install of Windows 10 and I was transferring some big files from a Linux (fedora 31) PC to the Windows PC via SFTP.
During these transfers the filezilla client froze several times, completley locked up the PC for 10-20 seconds (no mouse movement), slow transfer speeds (1 file transferring on its own did 40-50MB/s if that).
So I've been fiddling about, using the PC normally and...the issue seemed to have cleared up...until I reboot the windows PC and have nothing running and the issue then returns.
I open several programmes and...the issue goes. So I've closed them one by one and the issue disappears when Skype (Windows version, not UWP/Windows store version) is open! Now transfers go at 110MB/s lag free.
Close skype and filezilla, open filezilla on its own and the issue is back.
I've noticed when Skype is open, one core (or logical processor) has 60-80% usage, another 40-50% usage and the rest minimal.
When Skype is closed, 1-2 cores are pinned at 100% and System Interrupts process runs at 9-10%.
I'm completely baffled by this and why Skype being open would suddenly make everything run normally.
Also, it only seems to be an issue with high speed transfers.
Also some extra messing around with figuring out how to trigger it working normally.
Flash videos in a browser make it run normally.
I loaded up a YouTube video in Chrome (HTML5). When the video was playing, FileZilla ran normally. When I paused the video, closed and reopened FileZilla, the lagging issue came back.
Any ideas at all what's causing this or how to fix it? Besides running Skype all the time I mean...
It really is the weirdest thing I've come across.
Thanks for any help you can provide.
