Ask HN: What Web server load testing tools are you using?

I've used JPerf before, and found it adequate for what I needed. As I understand it, it basically wraps JUnit test cases in independent threads and lets them all run. Depending on your server, this approach might give you the load you need.

+1 for Jmeter

I've been focusing specifically in performance and scalability for the last decade. The vast majority of problems that expose themselves under load or many-request scenarios are blatantly obvious in a profiler or tracing data access patterns. I recommend you start there, better use of time.

These are the 2 load testing tools I used so far.

Grinder - able to record the test and customize, codes are in python.

Selenium - record in firefox, able to run the tests onto various web browsers.

If it's a simple public facing site I'll throw ab (Apache Benchmark) at it. I've used Pylot for more advanced stuff, although I know it's not particularly mainstream.

What if it isn't? :)
