for general performance testing stuff, I have several performance articles listed on the links page http://wiki.apache.org/jakarta-jmeter/JMeterLinks.
If I compare JMeter to other tools I've used, I would say it is comparable. The tools I've used: 1. apache ab 2. zdnet Webbench 3. custom script perl The biggest challenge of stress testing is this, "what are you testing?" Most of the time, the bottleneck for a website is the connection to the internet. I have a explanation of it in the articles. It doesn't really matter if your website can handle 80 concurrent requests reliably, if you're server is on a T1. I would say JMeter can easily produce enough stress to figure out what the upper limit is for your web application. The situations where it won't be suitable is if you're testing a system that has to support 5,000 concurrent users. You still could use JMeter if you setup each instance with 100 threads and use 50 machines. realistically, to do that kind of test, the server would have to be a big Unix box or mainframe hooked up to several gigabit routers. Using 100mbit ethernet, you wouldn't be able to test 5K concurrent requests for a sustained period of time effectively. Sustained transfer rate plays a huge role in how many concurrent requests a system can handle reliably for a long time. peter On Thu, 15 Jul 2004 11:25:50 -0400, joelsherriff <[EMAIL PROTECTED]> wrote: > After Peter pointed out that the jmeter proxy doesn't do ssl, I thought I'd > ask everyone if they know of other limitations they've run into and about > what seems to be the cronic limitation of these tools - scalability.
