Re: About the web polygraph to test squid performance

Thanks a lot for your helpful reply. I will try mix-4 instead .

Actually I just set a simple test: three server , one running squid ,
another two running ploysrv , poylclt seperately.

Can you give me some clue about how to modify PolyMix-4.pg ?

how can I set IP ?

        client_side = {
                addr_space = [ 'lo0::10.101.0-123.1-250/22' ];
                hosts = [ '172.16.101.61-62' ]; // replace with IPs of
your PCs
        };
        server_side = {
                addr_space = [ 'lo0::10.101.128-251.1-250:80/22' ];
                hosts = [ '172.16.101.191-192' ]; // replace with IPs of
your PCs
        };

What is the reasonable value for peak_req_rate & FillRate ?

How about if I have no dns server in my private network ?

Can I ignore it?

Thanks a lot!
