Speed issues could be explained as disk death. Those requests are
software issues somewhere. The via setting should clear them up.

For a quick check the cachemgr info page or "squidclient mgr:info"
command line shows a spot-check summary of the most useful/important
stats. FD, hit ratios, cache size, memory, service times etc.

For deeper monitoring there is SNMP counters that can be graphed or
whatever.
