Hii...

Am sure you are much aware " Components Response Time spectrum"

########Analyzing Performance Problems#################

--High wait time: Insufficient number of free work processes

--High roll-wait time: Communication problem with GUI, external system,

or large amount of data requested

--High load and generation time: SAP buffers (Program, CUA or Screen)

too small

--High database request time: CPU/memory bottleneck on database server;

communication problem with database server, expensive SQL statements,

database locks, missing indexes, missing statistics or small database buffer(s)

--High CPU time: Expensive ABAP processing, for example, processing

large tables; inefficient programming

--Processing time more than twice CPU time: CPU bottlenecks

If time aloows look at

Note 0000008963 - Definition of SAP response time/processing time/CPU time

Good General Performance Indicators.....

---

Wait time < 10% response time

Average roll-in time < 20 ms

Average roll-wait time < 200 ms

Average load (and generation) time < 10 % of response time (< 50 ms)

Average database request time < 40 % of (response time - wait time)

Average CPU time < 40 % of (response time - wait time)

Average CPU time not much less than processing time

Average response time depends on customer requirements; there is no general rule

--

You can use above benchmarks for quick winning on understanding.

Hello Prakash,

via transaction ST03N you could application servers and response times in different periods.

You could see as well how the response time is distributed,

Hello Prakash,

you could see in the ST03 how the average response time is distributed:

database time

roll+watit time, etc

depending which part of the response time is higher you could point to the performanc issue.

SAP Note 203924 provides information for interpretation of response times
