[KLUG Members] slow samba performance...

[Ron Sweeney]

Mark,

I have had success in tweaking Samba by setting the TCP delay options:


local area network install of Samba:
socket options = IPTOS_LOWDELAY TCP_NODELAY

wide area usage:
socket options = IPTOS_THROUGHPUT TCP_NODELAY

The TCP_NODELAY seems to have the biggest impact for most networks. I
have gained noticeably by dropping the following into
/etc/samba/smb.conf...

socket options = TCP_NODELAY

Use Ethereal to give you a tcp stevens graph for before and after perf
snapshots...



Hope this helps...
