Hi,

what is the meaning for "Select loop called: 730321522 times, 0.117 ms avg"

squidclient mgr:info

Connection information for squid:
     Number of clients accessing cache: 0
     Number of HTTP requests received: 32626996
     Number of ICP messages received: 0
     Number of ICP messages sent: 0
     Number of queued ICP replies: 0
     Number of HTCP messages received: 0
     Number of HTCP messages sent: 0
     Request failure ratio: 0.00
     Average HTTP requests per minute since start: 22877.7
     Average ICP messages per minute since start: 0.0
     Select loop called: 730321522 times, 0.117 ms avg <-----------------

Is it showing that , squid does in/out for objects with this (730321522)
times. is it right perception?

My full output of squidclient mgr:info. Please tell me that my squid is
performing well or do i need to do more tuning or something?
