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. Adrian
