Hello

1. ST05 - Trace requests

2. SE30 - Runtime analysis

3. SE38 -> Environment -> Perfomance examples

[former_member194613]

If you want to know all then you should start reading, tcodes will not help you.

I can offer you seven blogs:

SQL trace:

SE30

Measurements on internal tables: Reads and Loops:

How to Measure Operations on Internal Tables

Nonlinearity: The problem and background

Z_SE30_COMPARE

Nonlinearity Check

when you read them all, and understand them, then I would maybe

send you some more unpublished one

hi

i'm just read them all

i almost understand them and i'm really wonder that you said - unpublished one

can you tell me that one?

Hi Nishant.

Transaction code for performance tuning:

SE30 - ABAP runtime analysis

ST02 - Tune Summary.

ST03 - Workload Analysis (Tuning of buffers,.

ST04 - Database Performance Analysis.

ST05 - Performance Analysis (SQL Trace, etc).

ST06 - Operating System monitor.

ST07 - Application Monitor.

ST14 - Application Analysis.

this is a two year old thread, I wonder who finds this still interesting. I wonder even more that some references are many years old.

Unpublished blogs, don't know whether I will publish them. All I have to say about ABAP performance is published in my

book (however only in German):

you need performance tuning because of large amout of data. if your program give output very late then be patient. analysis whole program when you want to do performance tuning,  many tcodes are available SE30,ST02 TO ST07 AN ST14. but take simple method.

dont go with any tcode. which program need performance tunning execute it and open sm66.

and check if any query  take loge time to fetch data from internal table then put secondary index in that select statement.

second thing check whole program and void use nesting loops in that program.

also use BINARY SEARCH in read statement.

Don't use BINARY SEARCH. Use a HASHED table or a SORTED table. Thread locked due to age.

Hi, here are some wiki pages that summarized the ABAP performance tools centrally, including resources for further reading, e.g. Note/KBA, SAP online help links, or other wiki pages for the individual tool.

• https://wiki.scn.sap.com/wiki/display/CPP/Performance+Analysis+Transactions+and+Tools
• https://wiki.scn.sap.com/wiki/display/ABAP/ABAP+Test+and+Analysis+Tools
• https://wiki.scn.sap.com/wiki/display/CPP/Cross+Platform+Performance
• https://wiki.scn.sap.com/wiki/pages/viewpage.action?pageId=471175469 (Performance Analysis SAP Notes/KBAs)

I hope the above information is helpful like other answers on this page. These wiki pages are created in recent years, and they are under maintenance. It means that when there is some new information about this topic, the new information will also be merged into the above wiki pages.

For example, recently there is a new tool "profile data analyzer" which is a standalone tool to systematically analyze and visualize SE30/SAT trace and create analysis reports. The information for the profile data analyzer is also merged into the above wiki pages. (BTW, profile data analyzer also supports *.prf file from SAP JVM Profiler)
