Code checking

Question

Hi experts,,
In real time we will develop programs as per client requirement Ok,
If I want to check the performance of particular program where I have to check
Plz tell me ,
Points Will be rewarded
Thanks ,

Answer 1

The STAD gives you an overview on the runtime, it will not tell whether the performance is good or bad.
There is anyway nothing which can answer this question. However, the traces tell you whether there is room for improvement. I have written 2 blogs on the SE30 and ST05 which tell you details.
SE30

SQL trace:

In newer releases there is the code inspector available (tcode sci) which analyzes the coding.
The traces analyze the execution which is always an advantage, but more complicated.

If you want to process mass data then you should check scalability. For an introduction read

And the tool to confirm scalability is explained here
