I am investigating a web site response time issue that one of our patrons is having. After ruling out the obvious, I ran a tcpdump, and compared the packet trace to other web sessions that had reasonable response time, and found that the session that was having problems had a mss of 536, while most of the tcp sessions used a mss of 1460.
When I upgraded the kernel from 2.4.0-test12 to 2.4.0, response seemed to improve slightly. Nonetheless, I'm still seeing the same basic behavior: a burst of traffic, followed by a period of silence. I'm not an expert at analyzing packet traces, but it looks like the server is having to do a lot of re-transmits. The user states that other sites come up fine, including another web server that shares the WAN link with us.
Am I possibly looking at a kernel networking issue? What other things should I be looking at/for?
Thanks.
