Another possible issue is that squid is having to wait on a slow DNS
server. Take a look at the mgr:info report:

$ /usr/sbin/squidclient mgr:info

And look at "Median Service Times" section. In our case, DNS lookups
were in the 5+ second range, due to the primary DNS server being broken.
  So squid was asking the primary DNS server, waiting 5 seconds, then
asking the backup DNS server. A normal squid server will be servicing
all requests in under 1 second (depending on your load).
