I have a Spring batch application that runs in the VM, it takes 2 hours to process 10k records.

We are planning to migrate the application to Azure kubernetes and I see that the migrated application takes 6 hours.

I need to make the necessary changes to meet the current performance.

We didn't make any major changes in the code.

How do I do profiling to analysis the performance issues in Intellij? Is there any other way to find the cause for the performance impact.

Note : I don't have appDynamic.

The question is not really specific to Spring Batch per se, but if you want to profile a Java application with IntelliJ IDEA, you can run the app from within the IDE (or outside the IDE) and attach a profiler to it, see Profiling tools. This feature is only available in IntelliJ IDEA ultimate edition.

There are open source profilers that you can use as well, see Open Source Java Profilers.
