title: Squid best practices for caching
body: <p>I have setup squid in for caching and have used pointers from <a href="http://blog.last.fm/2007/08/30/squid-optimization-guide" rel="nofollow noreferrer">Last.fm post</a>. </p>
  
  <p>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?</p>
  
  <p>I have tried using tcmalloc, and disabling ESI but none of this help. </p>
