Re: Which statistic counter shows throughput

Hi Alex,
 Thanks for your answer.

 I am using Redhat Linux ES 3.1. gnuplot has been
installed. I ran gnuplot and got below info:

        G N U P L O T
        Version 4.0 patchlevel 0
        last modified Thu Apr 15 14:44:22 CEST 2004
        System: Linux 2.4.21-4.ELsmp

I ran reporter as below:
./reporter --label "Test" /opt/polygraph/polygraph.log
 --plotter /usr/local/bin/gnuplot

The error message is:
plotter location must be specified

I have reinstalled web-polygraph, but i still got this
problem. Do I have to specify any option for
"configure" ?

Another questions:
I uses simple test, req_rate = 1/sec, number of robot
= 800, size = exp(13KB), I can gain around 677
requests/second. 

If i change size = exp(80KB), I can gain around 119
requests/seconds.

For both cases, CPU used by Squid process ranging from
19% to 25%.

My question is why the number of requests/second drop
down too much like this?

FYI: I ran both polyctl and polysrv on another Redhat
Linux ES 3.1 server. I have two identical DEL servers,
Intel XEON 2.5 GHZ, 3x36GB HDD, RAID 5, 2 GB RAM. One
server installed SQUID 2.5.STABLE10 and the other used
as test client (run polyctl and polysrv). The link
between 2 servers is 100 Mbps.

I want to know the best throughput of my cache server.
With different test cases, I got different throughput.
For the same test case, it seem to result to the same
throuthput dispite the size of test object is
different.

Regards
Quang
