Are you absolutely sure you want the kill-parent-hack option?

This is a huge number of filedescriptors.. you will get better performance
if the number of filedescriptors is in balance with the numberof
concurrent users you have..

SMP is a waste for Squid. Better with two smaller UP boxes (and often
costs about the same..)

This you do not want if you are looking for good performance.

You'd also want to turn off half_closed_clients

Not many at all.. you should not need to make any tuning of your Squid.
