hello,
so my small test-case is doing the following (sorry i don't have the code here):
- JSP takes username and password and calls a "validate" method on a SLSB
- SLSB validates the given strings against hardcoded values and sends back a status (accept,decline)
for testing i use the performance tool openwebload (
http://openwebload.sourceforge.net) which gives the possibility to simulate concurrent access by more than one users.
i ramp up from 300 to 600 concurrent users and notice the maximum TPS of about 400 - 450 TPS.
another thing i realized is that the cpu on the server machine is utilized 100% during testing but the memory usage does not increase with the amount of users (stays at 50%). imho that is a very strange behaviour.
if you want i can post the code (which i think is not that interesting) and the detailed openwebload output later when i am at home again.
thanks for help,
mario
