See the FAQs:
http://curl-loader.sourceforge.net/doc/faq.html#statistics

It is stated:

"Some strings from the file:

The bottom strings after asterisks are for final averages."

Sot:
"Run-Time" is a time in seconds, "Req" is number of requests,
the bottom string after asterisks are really numbers for final averages.

Moreover, using this file one can make a graph of CAPS changes upon a time.

Indeed, time scale has been missed from the FAQs - the place to improve
on our side :) Thank you for the point.

"Session" is not clear what is it?

"Clients" raw in the same file .txt contains really number of clients.
If the number of clients is increasing you can graph, calculate, etc
being in possession of both time and clients numbers.

There are two modes of increasing number of clients: automatic, managed by
the CLIENTS_INITIAL_INC value and manual from the console. Y may wish to look
for that in FAQs.
