.SH DESCRIPTION
.B ab
is a tool for benchmarking your Apache HyperText Transfer Protocol (HTTP)

.B \-k
Enable the HTTP KeepAlive feature, i.e. perform multiple requests within one
HTTP session instead. Default is no KeepAlive.
.TP 12
.BI \-n " requests"
Number of requests to perform for the benchmarking session. The default is to
just perform one single request which usually leads to not very representative
benchmarking results.
.TP 12
.BI \-t " timelimit"
Seconds to max. spend for benchmarking. This implies
a
.B \-n
.B 50000
internally. Use this to benchmark the server within a fixed total amount of
time. Per default there is no timelimit.
.TP 12
.BI \-c " concurrency"
Number of multiple requests per time to perform.
Default is one request per time.
