I am not really sure how high the interrupts are allowed to go...

As you see - you have a quite a high IOWait, and high number of
interrupts.
CPU User is NOT the problem. I would take this to mean either disk or
network issues.
Is the latency on sites in the cache? or 'new' sites?
Hmm i'll see these but eg. openning googll site with squid enabled
take 1-3 sec.with squid disabled take max 1 sec
Are you running as a 'transperant' proxy? or have the users
entered the proxy details per
hand or per proxy.pak.... ?
transparent with iptabes redirect command from port 80 to port 3128.
Do you have this problem as well when you do NOT run in transparent
mode? (But still via proxy)...
I would probably run aufs rather than diskd - but this should not
make a real difference..
You have also only configured 3Gs of cache (3x 1G)...
You may want to try disabling the disk cache altogether and see
how that works - you need to
compile with -enable-storeio=diskd,aufs,null
cache_dir null ? in squid.conf ?
cache_dir null /tmp
this will cause squid not to cache to disk (well not really anyway)
I would also increase my cache size to perhaps, 2G.. (How much RAM
does the machine have?)
2 GB RAM
Try increasing your cache size to 1G, and disabling the disk cache..
- - see if that improves the
matter at all.
Stupid question - are you actually gaining anything by caching this
data? as I can not imagine
that such a small cache (3G) actually helps in any way. You must have
a pretty low hit ratio..
Summed up:
1. Disable transparent caching and try normal browser caching - does
this help?
if this doesn't change anything then try
2. change "cache_dir null /tmp" and increase you cache memory to 1G
Cheers
