Hi,

until yesterday I was convinced that WebTest was not an appropriate tool for load testing. A mail from Serban Balamaci on htmlunit's user mailing list seems to show that I was perhaps wrong:

-------------------- Well actually I'm using it as a load testing tool. I load up to 350 threads on one machine. I upped the memory to max 512M of my 1Gig system. I could even go higher with the number of threads. But i choose to be able to do some work on my laptop as well so i use 3 other machines that do the same thing and then consolidate my results into one doc. I even have ajax that is processed in my pages. No problems so far, besides some problems with varios javascript parts that were not necesary in the bussines flow.

I use in every new spawned thread a new instance of WebClient, as i need to simulate users with different sessions. Works very good, and at that time that i tried htmlunit was actually my only choice to process ajax requests. So "is htmlunit the best tool for load testing?". Answer: YES. Nice work HtmlUnit. --------------------

Marc.
