Samba 3.0.1 read performance problem

[Gerhard Wiesinger]

Hello!

I have a 100MBit switched network and run Samba 3.0.1 in a Samba
2.2.8a domain (3.0.1 because of valid users = %S, and write list = %S fixes) on Fedora FC1 with
latest fixes.

Read performance from Linux to Windows 2000 SP3 is very low
(around 2 to 4 MByte/s). Write performance is ok (>10MByte/s).

I already used
socket options = TCP_NODELAY SO_RCVBUF=8192 SO_SNDBUF=8192
(which is the performance optimum, other values are lower).

Netio and ftp performance is >10MByte/s, in most cases >11MByte/s (for
reads and writes)

Server: Linux Fedora FC1 with kernel 2.4.22-1.2149.nptl on an Epox 8KRA2+
Motherboard. Network adapter is a Gigabit Ethernet from Longshine
(rtl8169 driver).

No special configuration is used.

Any ideas?

Thank you for the answer.

Ciao,
Gerhard
