Do some profiling to find out whether you're lacking CPU or IO grunt.
I started optimising the Squid-2 codebase to remove a lot of the CPU
hogs but its a big job and noone seemed willing to sponsor any work.

Try out the Squid-2-HEAD codetree and see if you notice any difference.
There's plenty of work that can be done to Squid-2 to really cut
back on the CPU overheads but *shrug* noone showed enough interest.
