* Upgrade to squid-2.6.stable13. You'll thank us. The performance increase
  ove Squid-2.5 under Linux is going to be very noticable.

* Install a pair of disks running AUFS, not diskd

* Give the cache, say, 256 or 384 mb cache_mem; leave the rest for Squid
  indexes and unix disk caching

* Read the FAQ on Performance Tunning under Linux; google for it too.
  You might find a few variables in /proc to set to optimise stuff.
