> 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)
> 			     --------------       	       -----------
>     10 threads  - 1105.530784		  545.9761944   
>     20 threads  - 635.3480599	          556.6025772
>     30 threads  - 411.2374179             550.5108726
>     40 threads  - 215.8165598             570.8683581
> 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 ?
> My Setup:
> ---------
> Red Hat Enterprise Linux ES release 4
> Axis2 version 1.0
> Tomcat 5.5.17
> jdk 1.5.0_04
