> I've been running a few performance tests on Axis2 to compare it with Axis1. 
> I've found that when I post requests using a multithreaded http client [ that spawns
multiple threads each sending a certain number of requests ] , the performance of Axis2 seems
to degrade, whereas that of Axis1 seems to be relatively stable when tested using the same
client. 
> Here are the figures I have got. Each thread sends 1000 requests.
> I have measured throughput by measuring the time taken for all the threads to finish
and then calculating requests per sec.
> 			  Axis2(req/sec)	   Axis1(req/sec)

> Apparently, as the number of threads increases, the performance drops in Axis2 whereas
it remains reasonably stable in Axis1.
> Can someone tell me the reason for this, and is there any way the performance with multiple
threads in Axis2 can be made better / stabilized ?
