I want to isolate the processing time for each component when PSP is enabled.

Question

When I run a process like Read CSV File → Write CSV with PSP enabled and check the processing time in the XML log, it seems that the writing process is taking a lot of time.
Is there a way how to isolate this, as I would like to know the exact processing time for each component?

Answer

When a process such as Read CSV File → Write CSV File is executed with PSP enabled, reading and writing are executed in parallel, so due to the specifications of PSP and XML log, more processing time is output for Write CSV File in the XML log.

Therefore, you can check the processing time for each component in the XML log by disabling PSP and running the script.

If it is difficult to disable PSP, in a production environment for example, please consider creating a script that executes only the read component for investigation to isolate the processing time.
