Getting CPU time limit exceeded error while updating cases using custom mass edit functionality.
I have created visualforce page to mass edit the cases. While updating cases I am getting CPU time limit excceded error.

I have checked debug and found it is taking time to execute process builder and workflow rule. Arround 80% time is taken by process builders and workflow rules. I tried to optimize process builder but it is not working when I am deactivating process builder, it is working fine.

What could be the isuue?
