Q: 

Squid best practices for caching

I have setup squid in for caching .. and have used pointers from Last.fm post.

Though I have high capacity servers, since Squid is able to use only processor core, the CPU usage seems to be really high. Is there a better way to optimize squid to use less CPU ?

I have tried using tcmalloc, and disabling ESI.. but none of these help.
