Don’t know if you’ve ever had a need to do scalability testing, but I’ve always been a bit interested, and I thought I’d track down some tools.
Anyways, last night I began playing around with Apache JMeter and it’s pretty darn cool. It’ll simulate a bunch of threads/users, and give you a cool graph to check out as well. It’s a bit of a pain to configure (but the manual is very good), and you can set it up as a proxy and just capture your script directly from your browser (which is pretty darn cool - and time saving).
One this I have noticed is that Jmeter runs slow under JDK 1.3. Every time it hits a redirect it waits for 20 seconds. Run it under 1.4, and life is great! Must have been some tweeking in URL timeouts between those versions.
Anyways, recommended.
