[squid-users] still having performance issues

2007-08-08 Thread Scott B. Anderson
I've worked with Henrik on this some already, and we figured out some DNS 
issues and stopped connections from never completing but I'm at a loss as to 
what would do this:

(output of the squidclient mgr:active_requests for this one request. )

This file is 10401 KB long, and it took 10 minutes to download via squid. That 
means it is running about 150-200Kbps instead of 8000-9000Kbps. Same file 
without squid takes about 12 seconds. The connection is a 10x10Mbps fiber 
connection.

The squid server is the lan router and the client default gateway so any 
network issues would show up when proxy is off. I'm at a loss. This is 
2.6STABLE_13 on Fedora core 5 kernel 2.6.17-1.2174_FC5. This became a problem 
only after switching from a 4x2MB cable modem connection with static ip 
addresses to the new 10x10Mbps fiber connection with a full 32 static addresses 
in a /24.

The server is a single cpu Xeon @2.8 Ghz (family: 15, mode: 4, stepping: 1) 
with 1 GB ram (200MB-300MB free at all times)

what mtu size does the fiber connection have ?

maybe you could set the mtu size of your outgoing interface from
squidserver to a smaller value like 512Byte.

In the past we had a performance problem through a vpn connection and
solved it with a smaller mtu size, so no fragmentation has to be done.
