Increasing working processes in XI for tuning?

[Former Member]

Hi,

wie have a XI-system (4 CPUs, 64 GB memory,...) - a pretty good system. Now I saw, that the number of working processes is just 8 (a default installation).

I read, that RFC-connections need working processes and a context switch between Java-Stack and ABAP-Stack is working via RFC.

So I think, it's better to increase the number of working processes (e.g. to 20).

Any experiences in increasing working processes in XI?

Thanx a lot,

regards

Hi Wolfgang,

take a look to:

Note 894509 - XI Performance Check (see attachment: XI_Performance_Check_Version1.pdf)

Hope this help

Wolfgang Hummel,

As per one of the tuning guides from SAP,

no of WPs is approximately equal to 4 times the number of CPUs.

20 or even 16 (4 * no of CPUs) makes sense.

good luck
