I am on MacOS Catalina 10.15.7 and after closing a project I see the IntelliJ Welcome Screen. I opened Activity Monitor and noticed that there are 70 threads associated with IntelliJ IDEA.
What is this activity and how can I minimise it?

This is a screenshot 1-2 minutes after closing a project and on the welcome screen.

It looks like it is expected number. I see about same result. To see what threads are executed please take several Java thread dumps. Use:

  • Cmd+Shift+A
  • type "Dump Threads" 
  • hit Enter

to dump java threads of the IDE process. Take several thread dumps like this and attach it to see. Thanks.
