Samba mapping response times

[fbi]

We have an HPUX Environment which is allowing Windows 2000 workstations to mount to HPUX SAMBA shares. File accesses (reads/writes/etc.) to these shares are noticebly slower than identical operations to Windows 2000 Server shares. Is there an ideal smb.conf configuration which will maximize access speeds to/from these Unix SAMBA shares?

Shalom,

Before you start working on smb.conf you might wish to correctly identify the problem.

The response issue could be due to dns lookup speed, network problems, system load or any number of things.

Samba's default configuration file gives very good performance and even scales well, all other factors being equal.

Get real performance data.

That being said if you want to play:
socket options = TCP_NODELAY SO_RCVBUF=8192 SO_SNDBUF=8192

These optoins seem to improve performance. I'm not sure if the options are standard, you should check.

Send me an email and I will send to you my HPWorld 2003 CIFS Tuning presentation. There are too many variables to list, but this .ppt hits most of the Samba related issues.
