"""CherryPy Benchmark Tool
|
|
|
|
Usage:
|
|
benchmark.py [options]
|
|
|
|
--null: use a null Request object (to bench the HTTP server only)
|
|
--notests: start the server but do not run the tests; this allows
|
|
you to check the tested pages with a browser
|
|
--help: show this help message
|
|
--cpmodpy: run tests via apache on 54583 (with the builtin _cpmodpy)
|
|
--modpython: run tests via apache on 54583 (with modpython_gateway)
|
|
--ab=path: Use the ab script/executable at 'path' (see below)
|
|
--apache=path: Use the apache script/exe at 'path' (see below)
|
|
|
|
To run the benchmarks, the Apache Benchmark tool "ab" must either be on
|
|
your system path, or specified via the --ab=path option.
|
|
|
|
To run the modpython tests, the "apache" executable or script must be
|
|
on your system path, or provided via the --apache=path option. On some
|
|
platforms, "apache" may be called "apachectl" or "apache2ctl"--create
|
|
a symlink to them if needed.
