RFC & SAP Performance

[Former Member]

Hi,

We have a situation where Web Portal makes an RFC call. We are thinking about limiting the number of users that can log onto the portal simultaneously.

What are the performance issues related to maximum number of simultaneous calls to this RFC? If say 100 log into the site simultaneously, 100 RFC calls would be generated. Will there be any performance related issues?

Thanks

normally there should not be any problem...We are having same situation wherein almost more than 1000 people access the system remotely at a time and it has never gone into performance issue....Try checking ur system.

Thanks for ur reply Ramesh!!

Right now we are just considering the design & performance issues for the system. Would the amount of data returned by SAP somehow affect the performance?

Hello,

Generally if data is structured properly,it should not create problems.

What causes problem for such RFC calls is amount of time SAP takes to respond .If you have RFC which is not wirtten in good way (for optimised performance) then SAP takes lots of execution time to return data back to calling application & that sometimes is an issue for users who would not like to wait for 30-40 seconds just to get some data based on which they will go ahead & decide further actions.

Hope this helps.

Thanks.

Hi Rushali,

Thanks!!!

Just wanted to know if there is some limit to number of simultaneous execution of the same RFC function module before (otherwise good performance) degrades in performance?

Munish,

Talk with your basis team to find out how many RFC threads could be executed simultaneously. There could be a limit.

This was taken care of by the Web Team.
