Hi,
there was one the performance analyzer compliance flag in the PS toolkit for tracking RPC, download ans JS.
You used to add ?performance=1 to the Web app URL and see time for each line being executed.
Now this tool has been removed.

So, first of all, I suggest now you read this doc

https://www.appeon.com/support/documents/appeon_online_help/2017/appeon_performance_tuning_guide/ch01.html

It will explain slow code usually belonging to:
1) heavy PScript
2) multiple server calls

For 1) you need to simplify legacy code (heavy menu(s) iteration, complex string manipulation, loop over nested objects on a window, resizing, etc...).
For 2) you can learn how to group independent DB requests and reduce network latency.

As time goes by, you will learn how to recognise slow code.

Best,
.m

Hi Saravanan;

  PS does not support the "trace" feature like native PB App's do. Instead, have a look at the "Debug Trace" feature as listed in the PS documentation. It's activated via the AEM console application for each PS application as required.

HTH
