Re: Overhead of SCA Native Container

[roshan joseph <ro...@yahoo.com>]

Hi Andy,
   I have run my above test in Apache 2.0 httpd server with axis2c 0.96 version and could get a decent timing for my web service SOAP test. 
   
  At times for a 300 user test it gave me an average time of 6millisec for a load of approximately 393 bytes soap request and the throughput is 14.9 messages per second, with zero errors. If I increase the test to 600 users it gave me a throughput of 29.4 msg/sec and average time is 5 millisec. 
   
  This is the best case scenario, but at other times even for a 50 user test it gives memory exception and on going to debug mode I get this unhandled exception which I have updated below (the output window messages). Some SOAP request takes a lot of time and is successful, but most of the SOAP request fails. 
   
  The best_case/worst_case scenario is 50/50 and hence reliability is problem here.
   
  Is this a problem with the axis2c soap engine or a Tuscany problem, can you give your comment based on this output msg…
   
  If anyone else has an opinion on how to resolve this exception please comment, it will be of great help for me.
   
  Regards
  Roshan
