In our application while fixing the performance guardrail warnings we have observed the performance warning as "post processing activity of a flow action should start with post". I didn't understand how the name of the activity will have a severe impact on the performance of application. Could any one please suggest me.
What version of the system are you using? I was able to add a flow action with a post processing activity and wasn't able to see that warning in a Pega 7.2 system. Also, it might be helpful to be clear where you are seeing this warning from, since it's possible I'm just not reviewing the correct landing page.
