What exact performance gains did you see, curious to know a number and a lil' more on env.
Necropost alert but it bugs me your question wasn't answered... I ran into this looking for help for SMB woes on r151038.
Thank you!
I have an Intel X540-T1 in my NAS running omnios-r151038 on a SuperMicro X9SCM-F mobo.
Pulling my hair out trying to get SMB to break 100MB/sec when copying files from windows 10 to the SMB share.
Apparently ip_lso_outbound is set to 1 by default on this release of omnios:
Code:
# ndd -get /dev/ip ip_lso_outbound
1
Created a file in /etc/rc3.d called S98ndd_lso and put the " ndd -set /dev/ip ip_lso_outbound 0 ".
Code:
# ls -l /etc/rc3.d/S98ndd_lso_outbound
-rwxr-xr-x 1 root root 35 Jan 9 09:52 /etc/rc3.d/S98ndd_lso_outbound
# cat $_
ndd -set /dev/ip ip_lso_outbound 0
I also changed the buffers with ipadm as suggested (those changes were persistent).
5x speedup!!!
now hovers around 550MB/s (and sometimes breaks 600MB/s) when dragging and dropping large files from my W10 box to the SMB share (zfs pool) on my NAS.
