Re: [squid-users] suggestion ..

I think, that switching over to the new machine will improve the
situation. Spec looks more than sufficient for your number of users
when you have more than one disk.

Squid will use only one processor, the second will help when deploying
squidguard or other services on this machine. I am not sure if the
second processor will be used by squid when running with aufs - ask the
list.

You have a good uplink, we serve 1000 Clients (roughly 150 connecting at
the same time) with 5Mbps ADSL with good service times.

40 GB IDE disk (4 partition, each 5 gigs for cache): Does that mean 4
partitions with 10GB with a usage of 50% (5GB)?
Using a single IDE disk is an impact on performance.
Reiserfs is known to have a good performance when used for the cache
disks, you can use ext3 for the other partitions. Use more than 80% of
available space will impact performance as well - I prefer an even lower
usage.

More Info about RAM:

Monitor you squid with snmp and cachemgr. Look at the service times and
the general runtime information in cachemgr (
May be your machine is swapping already, this is an performance killer.
