I'm also experiencing this issue and I'm trying to fix this for days
now. The send speed caps out at about 700 Mbps. I'm not seeing any hangs
or connection losses though. I'm eager to find a solution for this, as I
have to move 50 TB over that server.
What I've tried:
- Kernels: 4.15.58, 4.15.60

I also encountered network performance degradation on my server, however I'm
not running Ubuntu but Debian with a self-compiled kernel. With bisecting the
kernel, I could track this issue down to this commit between 4.14.2 and 4.14.3:
While I was waiting for a fix, I've just noticed a new problem.. Now the
transfer speed became very inconsistent. For the first few seconds when
I'm sending TO Ubuntu I get 110MBs (as expected), but then speed drops
to 50, 30, 20 and keeps going up and down for the rest of the files
transfer. Very
I've just confirmed the problem again by trying to transfer a file
between Windows 10 and Ubuntu 18.04.1 via samba. Upload speed from
Windoes to Ubuntu is 110-115MB/S, while download from Ubuntu to Windows
is only 88-90MB/S.
There seems to be another possibly related or unrelated issue. If SAME
