BaukBench - HTTP/1.1 benchmarking tool


BaukBench is a HTTP/1.1 benchmark/stress test tool for measuring performance of Web servers.
Advantage of BaukBench compared to other HTTP benchmark tools is that it does not have limitations which produce bottlenecks to appear on side of client hence making impossible to measure Web server's max performance.
Ie. benchmark tool "ab" (ApacheBench) does not handle well large number of simultaneous HTTP connections, ie. over 500, and cannot bench dynamic content with KeepAlive connections. Benchmark tool "httperf" makes 1 second delay between requests, has no support for KeepAlive connections, etc.
BaukBench does not have these limitations and using minimum resource on client it is capable of producing extreme load for testing max performance of a Web server.

Benchmarking server on port 80, 10000 requests, 500 simultaneous connections,
using KeepAlive:

 $ ./bb -host -url /page.html -n 10000 -c 500 -k

Benchmarking PHP server, 4000 requests, 350 simultaneous connections, sending
cookie in request:

 $ ./bb -host -url "/script.php?abc=xyz" -n 4000
      -c 350 -k -cookie "XYZ=abc"

Example output:
 $ ./bb -host -url /page.html -n 10000 -c 500 -k
