Re: [squid-users] how can i get squid max performance

Thank you !
I would use this tool to monitor system when busy traffic.
And every squid box has about 5M/sec from mrtg graphs ,
and about 1800 ESTABLISHED from netstat .

You need to find out where is the bottleneck.
Are your squid boxes CPU bound? (Seems like not). Disk bound? Network bound?
Maybe you just reached your outbound connection's bandwidth?

40M/min? 40M/sec?

Here is a little tool I use to find out various statistics
of my boxes.

In case you will have difficulty compiling it,
I included static binary too.
