STAD : Processing time when calling c program

[Former Member]

Hi,

when I look at the central instance of our system, I see that much of the response time is recorded as "Processing time". Much more than 2 * cpu time. According to sap performance optimisation guide, this implies CPU or network bottleneck. We have no such bottleneck at this time.

I am wondering if the time spent in a c program when called from a function is recorded as processing time because the system has no way of calculating its ressource usage ?

Thank you

Apart from me stupidly adding CPU to my list of causes, I feel my call was succinct and answers your question mostly but I forgot to add that you are correct, the system has no way of measuring that time apart from as "call time" as already mentioned.

Please be careful with Tilak's response.. comments like Also, increase number of dialog workprocesses should only be done when it is clear that your Wp's are full due to there not being enough as opposed to another performance problems causing a queue... It is probably the most often suggested thing and the least required. each Wp uses 50-70 MB or non swappable RAM!!!
