JCo Connection Performance Tuninng

Former Member

Hi all,

Here's a performance tuning problem occurs when I do the Stress Test for a JCo Connection.

I call bapi with abap model autogenerated by webdynpro wizard, then I developped a method to do this post job(with same data, suppose each post get the right response) for 1, 10, 20, 50 times.

I found the first time it will cost a real long time(such as 21s) to get return, then performance can be better, an average time cost is about 700 ms.

So I think there must be someplace to cache the post data, if I can modify the size of the cache, maybe I can improve the performance.

Now the question is where is it?

Any idea?

Hi Bertram,

Is there any code I should add in my web Dynpro Program to close the JCO connection. I am using JCO connection maintained in content administrator using JCO pool configuration.

Still when I check SAP R/3 many sessions are opened and I am closing those manually.

Your help appreciated.

Thanks,

Rakesh
