- Urgent
I've been encountering some weird performance issues with 6.10.0-rc2.
I'm using 1 Gbit/s connections both with my Unraid server and my Desktop PC.
This is what it looks like transfering a file from my Kingston A2000 in my Unraid server to my Desktop PC (this is via FTP; the same goes for SMB):
This is what it looks like transfering a file from my Desktop PC to my Unraid server via FTP (the same goes for SMB):
This is almost 3x faster, which should not be the case given that it's a working 1 Gbit/s connection to my router and going from my router to my Desktop PC.
And just for comparison's sake, this is an iperf3 test with my PC running as a server:

iperf3: error - unable to receive control message: Connection reset by peer
Something is clearly not working properly here, but I can't figure out what. This is a fresh install with just a couple of settings changed (like creating an FTP User and an SMB User) in addition to reinstalling my Docker containers. For this test though, Docker has been completely disabled.
I've attached a diagnostics file; maybe somebody can figure out what's going on.
