Subject: [CentOS] Performance problem with CentOs 4.4 Samba


Hello

I experience performance problem with CentOs 4.4 Samba 3.0

Reading files from Samba (1 client WinXP) is 3 times slower than writing 
to samba.

What should I look at?

OS je CentOS 4.4 (RHEL 4 U4)

# smbd --version
Version 3.0.10-1.4E.11

Try adding:

	socket options = TCP_NODELAY

to the [gloabal] section.
