Hi all,
I am trying to get some decent speed out of a vanilla Debian (Proxmox) box and
am running out of ideas. Basically I can exchange data at 110MB/sec (raw, nfs,
ftp) but not with Samba shares.
I tried almost every samba tuning tip I could find to no avail. The only
optimisation left to smb.conf at the moment is debug level = 0. As one can see
the robocopy throughput is merely half of what would be expected.
Any hints?
Best regards
Udo

If there is a socket options line in your smb.conf, comment it out and restart samba and see if your speed improves.

If so, you can enable it on the linux server: http://www.cyberciti.biz/faq/rhel-centos-debian-ubuntu-jumbo-frames-configuration/ Hopefully you can enable it on the workstation and switches. On windows clients you can also try SG TCP Optimizer from: http://www.speedguide.net/downloads.php What does you smb.conf look like? -- Regards -------------------------------------- Gerald Drouillard Technology Architect Drouillard & Associates, Inc. http://www.Drouillard.biz
