Hello there,

I'm wondering if there are some kind of minimum system requirements for the RAP client when deployed into a tomcat?

How many RAM would you suggest? Is there anything else to take care of?

And are there any "quick wins" for enhancing the performance in a tomcat environment too?

Thanks,

Peter

Hi Peter

I once measured the memory size needed to run a (big) scout RAP application (definition if big: several hundred UI classes - forms, tablepages and so on).

On tomcat, the RAP Server needs up to 500 MB of "base space" (after startup) plus 10-20 MB of space per logged in user (scout session).
A lot of the "base space" is consumed by non heap data. A scout RAP application needs to load a lot of different classes. So you will need to set the perm gen size accurately.

For a mid sized application, the "base space" should be ways smaller. For an accurate measurement, of course, you will have to measure your application.

Hope this helps.
