Testing Web Performance with httperf

I got another tool for testing webperformance. This tool is httperf. It was developed by David Mosberger from HP.

The installation process is very smooth and usual :

$ ./configure
$ make
# make install

Next I try httperf to issue 1000 HTTP requests :

$ httperf --server localhost --port 80 --num-conns 100 --rate 10 --timeout 2

The above command will create 100 connections during 10 seconds (1000 requests).

Here is the result (it is not pretty) :

Total: connections 100 requests 100 replies 100 test-duration 9.901 s

Connection rate: 10.1 conn/s (99.0 ms/conn, <=1 concurrent connections)

Errors: total 0 client-timo 0 socket-timo 0 connrefused 0 connreset 0

I leave the interpretation of the above statistics to the readers.
