Hi folks,
I am experiecing a performance breakdown when writing to some geom class
volume over network. I have tried SCP/SFTP, SMB, nc, ggated/ggatec from
Windows 10 and FreeBSD 10.3-RELEASE and I receive at most 500 kB/s.
Reading is superfast as well as writing to a regular, non-geom volume,
network is fully saturated.
I am on:
# uname -a
FreeBSD bsd1home 10.3-RELEASE-p7 FreeBSD 10.3-RELEASE-p7 #0: Thu Aug 11
18:37:29 UTC 2016
r...@amd64-builder.daemonology.net:/usr/obj/usr/src/sys/GENERIC i386
Any idea what the problem is? How can I investigate on the penality in
performance?
FWIW, this problem is unlikely rooted in geom at all. I have added a
second NIC into the machine, Reatek 8139 rl0 (yes -- I know it's crap),
and performed the same setup: maximum speed. Conclusion for me is rather
my NIC is broken or the driver. I suspect the driver to be.
The link state was going down and up over and over again. The same issue
has been reported here [1], [2] a couple of years ago.
I will repost this to freebsd-net or rather to bugs.freebsd.org
