RE: [squid-users] Squid - performance

Thanks
What parameter do I need to poll to check object hit rate?
There are other parameters also like Byte Hit rate, request Hit ratio
etc. How can I get detail on this. Is there any website for this?

Is it really impossible to get better performance and more caching up to
30%

Thanks - Lokesh

  None , squid will cleanup swap space automatically if needed to
  store new objects.

  Difficult , I have the same performance for a similar cache.
 Note that your object hit rate may be higher though.
