Apache HTTP Server Version 2.2
ab
is a tool for benchmarking your Apache Hypertext
Transfer Protocol (HTTP) server. It is designed to give you an impression
of how your current Apache installation performs. This especially shows
you how many requests per second your Apache installation is capable of
serving.

-q
flag will suppress these messages.-s
ab -h

protocol.
This feature is experimental and very rudimentary. You probably
do not want to use it.-S

fixed total amount of time. Per default there is no timelimit.-T content-type

.There are various statically declared buffers of fixed length. Combined with the lazy parsing of the command line arguments, the response headers from the server and other external inputs, this might bite you.
It does not implement HTTP/1.x fully; only accepts some 'expected' forms
of responses. The rather heavy use of strstr(3)
shows up top
in profile, which might indicate a performance problem; i.e., you
would measure the ab
performance rather than the server's.
