X proxy:port Proxyserver and port number to use P attribute Add Basic Proxy Authentication, the attributes A attribute Add Basic WWW Authentication, the attributesĪre a colon separated username and password. H attribute Add Arbitrary header line, eg. z attributes String to insert as td or th attributes y attributes String to insert as tr attributes x attributes String to insert as table attributes v verbosity How much troubleshooting info to print T content-type Content-type header for POSTing, eg. p postfile File containing data to POST. b windowsize Size of TCP send/receive buffer, in bytes c concurrency Number of multiple requests to make n requests Number of requests to perform As you can see there are many useful options for outputting results, and sending additional data in the request. The usage info from the ab version installed on my Mac (v2.3) is listed below. You will also want to redirect the output to a file for each URL using > filename For example: #!/bin/sh At the end of each line place, this makes the command run in the background and lets the next command start execution. Suppose you wanted to test multiple URL’s concurrently as well? You can do this by creating a shell script, with multiple ab calls. This is the php code that I’ve saved into a file named checkiffileexists.php: Pay attention to the performance statistics: Apache Performance Load TestingĪs you can see, the performance of the server with the event is highly superior to its prefork counterpart in every aspect of this test.
