Samba Performance Problem Due to Changing Linux Kernel
A user wrote the following to the mailing list:
I am running Gentoo on my server and Samba 2.2.8a. Recently I changed kernel versions from
linux-2.4.20-wolk4.0s. Now I have a
performance issue with Samba. Many of you will probably say, “Move to vanilla sources!” Well, I
tried that and it didn't work. I have a 100MB LAN and two computers (Linux and Windows 2000). The Linux server
shares directories with DivX files, the client (Windows 2000) plays them via LAN. Before, when I was running
the 2.4.19 kernel, everything was fine, but now movies freeze and stop. I tried moving files between the
server and Windows, and it is terribly slow.
The answer he was given is:
Grab the mii-tool and check the duplex settings on the NIC. My guess is that it is a link layer issue, not an
application layer problem. Also run ifconfig and verify that the framing error, collisions, and so on, look
normal for ethernet.
