From: Ashley Sheridan on 8 Mar 2010 12:37 Hi all, I was wondering if there were any ways to simulate loads on a PHP script running on the server? Basically, I'd just like to take one of my sites through a dry-run so to speak and simulate x number of visitors. Ideally, I'd prefer something that didn't have to be installed on the remote server. Also, it would have to be something I could use from within Linux, as I only have Windows running as a VM, and I'm not sure it would work as intended if run though a VM. Have any of you used such tools, and if so, are there any you'd recommend? Thanks, Ash http://www.ashleysheridan.co.uk

There's always Apaches "ab". Though I've seen it mentioned that the load isn't always realistic. -- Richard Heyes HTML5 canvas graphing: RGraph - http://www.rgraph.net (updated 6th March) Lots of PHP and Javascript code - http://www.phpguru.org
From: shiplu on 8 Mar 2010 13:35 You can use "siege" in command line for web server stress testing. There are other tools. I forget it. Just look at the Performance section in http://talks.php.net/ There are some slides of Rasmus Lerdorf about these on http://talks.php.net/ which are very helpful. -- Shiplu Mokaddim My talks, http://talk.cmyweb.net Follow me, http://twitter.com/shiplu SUST Programmers, http://groups.google.com/group/p2psust Innovation distinguishes bet ... ...

Since it is written in Java it will run just fine on Linux. Setting up a test scenario may take some time but it can browse your page like a regular user would (with delays) and supply input where required. This is executed from a client machine and does not require anything to be installed on your server. http://jakarta.apache.org/jmeter/ -- John |
