RE: Slow deserialization in axis

Aravind,

One problem with your approach is that you still don't know for sure if time is actually spent executing the deserializer.

Is it possible that the threads are waiting on something at that point? There are profiling tools out there that shows time spent

on specific calls. 

Just curious, what is your server environment?

Jai,

 

    I m using a threaded program to get 50 concurrent requests to my webservice. I enabled the  axis logging and ran my program. The axisServlet was called concurrently(log time indicated that) . so I assumed that there is no network problem.Then onwards each thread started taking its own time and when it reached my web service, only few threads were concurrent. I went thro the log created by axis and found that till de- serializationimpl all the threads were having same time consumption. Then they differed and every next thread took more and more time.  Then I tuned my server for accepting more concurrent threads and also increased heap.But there was no difference in result. Can you suggest me some other ways...

 

thanks

Aravind,

Our server does both serializations (but more bean) and we haven't noticed any significant performance problems with heavy loads.

Now, how are you determining deserialization is the problem? It can be caused by varous factors such as your network configuration,

app server scalability etc..

Its bean serialization. I m using  default setup of axis without changing anything.

Are you using bean or custom serialization?

Hi,

I have hosted a webservice using axis on tomcat 4.1.24.

I m finding that as concurent load increases, there is a tremendous growth in the deserialization time taken.

Any clues ??

Thanks
