Dear SQUID-expert frens,
We are experiencing slowness in surfing here. Just
want to find out, Which part of the cache manager
output that I should look into to check whether or not
the problems lies within SQUID. Kindly help.

Hit (the object is cached) service time in the milliseconds, miss (the
object is not cached) and near hit service time (Squid had to verify the
cached object is still fresh) in the tens of seconds and DNS lookups
(apparently) taking no time at all. Maybe it's just me, but I think the
problem lies outside of Squid.
