The test performs a 'POST' to a cgi script that returns ~60K worth of data. All
the cgi script does is sleep for 2 seconds, and
write output. The cgi script looks like this:
#!/bin/bash
sleep 2
cat <<!
Content-type: text/html
<html>
<head>
[about 20K bytes of useless stuff goes here]
</head>
<body>
[about 40K bytes of useless stuff goes here]
</body>
</html>
!
The cgi script doesn't attempt to process the POST at all, it just returns
useless data. The purpose of the test was to figure out
why JMeter was giving me such 'different' results between JM2.4 and JM2.6. I
think I've done that now - JM2.4 (on WinXP) wasn't
reporting the correct numbers in the Summary Report. Sadly this means that all
my prior benchmarks are nearly useless - since the
numbers there can't be trusted. But I can start a fresh set using JM2.6 now and
feel pretty comfortable that the numbers are at
least accurate now.

Hey
Is it the test considering the "CGI Script" as an addon which it
includes in a different hit to the server. And the average is the
"Average of two request, one to the original page and one to the CGI
Script"
Your answer is 2.5 seconds. 2 second for the CGI script and 0.5 second
for the overall transaction. It just treats the CGI script like an add
on file.
