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\&. + + +.SH "OPTIONS" + + +.TP +-A \fIauth-username\fR:\fIpassword\fR +Supply BASIC Authentication credentials to the server\&. The username and password are separated by a single : and sent on the wire base64 encoded\&. The string is sent regardless of whether the server needs it (\fIi\&.e\&.\fR, has sent an 401 authentication needed)\&. +.TP +-c \fIconcurrency\fR +Number of multiple requests to perform at a time\&. Default is one request at a time\&. +.TP +-C \fIcookie-name\fR=\fIvalue\fR +Add a Cookie: line to the request\&. The argument is typically in the form of a \fIname\fR=\fIvalue\fR pair\&. This field is repeatable\&. +.TP +-d +Do not display the "percentage served within XX [ms] table"\&. (legacy support)\&. +.TP +-e \fIcsv-file\fR +Write a Comma separated value (CSV) file which contains for each percentage (from 1% to 100%) the time (in milliseconds) it took to serve that percentage of the requests\&. This is usually more useful than the 'gnuplot' file; as the results are already 'binned'\&. +.TP +-g \fIgnuplot-file\fR +Write all measured values out as a 'gnuplot' or TSV (Tab separate values) file\&. This file can easily be imported into packages like Gnuplot, IDL, Mathematica, Igor or even Excel\&. The labels are on the first line of the file\&. +.TP +-h +Display usage information\&. +.TP +-H \fIcustom-header\fR +Append extra headers to the request\&. The argument is typically in the form of a valid header line, containing a colon-separated field-value pair (\fIi\&.e\&.\fR, "Accept-Encoding: zip/zop;8bit")\&. +.TP +-i +Do HEAD requests instead of GET\&. +.TP +-k +Enable the HTTP KeepAlive feature, \fIi\&.e\&.\fR, perform multiple requests within one HTTP session\&. Default is no KeepAlive\&. +.TP +-n \fIrequests\fR +Number of requests to perform for the benchmarking session\&. The default is to just perform a single request which usually leads to non-representative benchmarking results\&. +.TP +-p \fIPOST-file\fR +File containing data to POST\&. +.TP +-P \fIproxy-auth-username\fR:\fIpassword\fR +Supply BASIC Authentication credentials to a proxy en-route\&. The username and password are separated by a single : and sent on the wire base64 encoded\&. The string is sent regardless of whether the proxy needs it (\fIi\&.e\&.\fR, has sent an 407 proxy authentication needed)\&. +.TP +-q +When processing more than 150 requests, ab outputs a progress count on stderr every 10% or 100 requests or so\&. The -q flag will suppress these messages\&. +.TP +-s +When compiled in (ab -h will show you) use the SSL protected https rather than the http protocol\&. This feature is experimental and \fIvery\fR rudimentary\&. You probably do not want to use it\&. +.TP +-S +Do not display the median and standard deviation values, nor display the warning/error messages when the average and median are more than one or two times the standard deviation apart\&. And default to the min/avg/max values\&. (legacy support)\&. +.TP +-t \fItimelimit\fR +Maximum number of seconds to spend for benchmarking\&. This implies a -n 50000 internally\&. Use this to benchmark the server within a fixed total amount of time\&. Per default there is no timelimit\&. +.TP +-T \fIcontent-type\fR +Content-type header to use for POST data\&. +.TP +-v \fIverbosity\fR +Set verbosity level - 4 and above prints information on headers, 3 and above prints response codes (404, 200, etc\&.), 2 and above prints warnings and info\&. +.TP +-V +Display version number and exit\&. +.TP +-w +Print out results in HTML tables\&. Default table is two columns wide, with a white background\&. +.TP +-x \fI<table>-attributes\fR +String to use as attributes for <table>\&. Attributes are inserted <table \fIhere\fR >\&. +.TP +-X \fIproxy\fR[:\fIport\fR] +Use a proxy server for the requests\&. +.TP +-y \fI<tr>-attributes\fR +String to use as attributes for <tr>\&. +.TP +-z \fI<td>-attributes\fR +String to use as attributes for <td>\&. + +.SH "BUGS" + +.PP +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\&. + +.PP +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; \fIi\&.e\&.\fR, you would measure the ab performance rather than the server's\&. + |
