Memory Usage By Unused Process Variables?

Hi Hitesh, Please follow the below article under Appian Playbook where it was mentioned in the second paragraph.

Hi Poorna,

The paragraph talks about the data being held in the process variables but if it is unused or not holding any data at run time, will it still occupy memory?Any more pointers?

Thanks.
Hitesh

The sentence - "The greater the number of process variables and the larger the amount of data stored in process variables, the more memory a process instance will consume." - says about the entire list of process variables that we keep in an instance (irrespective of using or not using them), as per my understanding. So, the unused variables also might occupy space in memory which need to be rectified from performance perspective.
To your second question, I am not sure whether we can find the same in some log or so.
