[squid-users] Understanding the stats.

Hi,

Looking at some stats from Cache Manager. I originally
thought there were just hits or misses, is a Near Hit
still a miss? I am hoping for a deeper explaination of
Near Hits. Also, can you guys tell me, but doesn't
this look like a poorly performing squid server?? It's
for approx 30Hours.
