How to understand the STAD relevant for RFC

[Former Member]

Hello performance experts.

I have question about how to understand the STAD relevant for RFC.

I want to know how to calculate the response time of action of "Push save buttion"

which call function module by RFC.

In our system, the screen is created using web dynpro and after push the button,

function module for application will be called.

When I push Save button, 2 STAD line is created.

One is for function code " SAVE" and the other is for "RFC".

Line for "SAVE" include RFC as client, and RFC line has RFC info as server (also client)

I wonder how I should calculate the response time of action"Save" button in following case.

Should I add the 2 response time?

1) 5,867 ms + 5,797 m is collect?

2) 5,867 ms include RFC time, so no need to sum the value and 5,867 ms is collect??

3) 590 ms + 5,797 ms is collect?

4) Or other calculation is correct ?

Hi Keiichiro,

I wonder how I should calculate the response time of action"Save" button in following case.
Should I add the 2 response time? 
1) 5,867 ms +   5,797 m  is collect? 
2) 5,867 ms  include RFC time, so no need to sum the value and 5,867 ms is collect?? 
3)  590 ms  +   5,797 ms is collect? 
4) Or other calculation is correct ?

It depends of what you mean with response time of action "Save" button.

If you mean ALL time, the value is 5.867 because the local time from save was 594ms, the "external" RFC time was 5280ms.

If you want separete analysis, the 594ms is your option since the 5280ms is in other part...

Also, analysing the other part there's another other part which represents a good part of processing time:

Database request time      2,882 ms

Hope this help youl.
