AUTHOR

This program and manual page was written by Radim Kolar, for the Supreme Personality of Godhead (but may be used by others).

DESCRIPTION

webbench is simple program for benchmarking HTTP servers or any other servers, which can be accessed via HTTP proxy. Unlike others benchmarks, webbench uses multiple processes for simulating traffic generated by multiple users. This allows better operating on SMP systems and on systems with slow or buggy implementation of select().

The programs follow the usual GNU command line syntax, with long options starting with two dashes (`-'). A summary of options are included below.

-p, --proxy <server:port>: Send request via proxy server. Needed for supporting others protocols than HTTP.
--get: Use GET request method.
--head: Use HEAD request method.
