There is no such degradation any more. Marking the bug as fixed.

> Project: Axis 2.0 (Axis2)
> Issue Type: Bug
> Components: kernel
> Environment: Red Hat Enterprise Linux ES release 4
> Axis2 version 1.0
> Tomcat 5.5.17
> jdk 1.5.0_04
> Reporter: Subramanyam Ramanathan

> 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
