I've been able to do a little more monitoring on squid - the DNS Lookups are
still below 1 seconds for the 5 minute averages during the times when there
is a slowdown in squid response. And the connections averages around 5 per
seconds, just like the time when there isn't a slow down...
Just wondering are there anything else that might be causing it?
For the short list (ordered by commonality I've seen):
* Disk I/O wait
* DNS lag
* RAM swapping (causing disk I/O wait)
* CPU overload.

We have squid running on a server with delay pools enabled. The
squidclient usually responds very quickly - in less than 0.03
seconds most of the time. However, there are times when this rises
to over 39 seconds.
There are 2 Gb of RAM, and there's about 900mb used.
There's 1024 file descriptors, and the largest opened hovers around
370.
Could anyone suggest what I should be looking for to track down why
squid sometimes take so long to respond? Thanks.
