Object Event Handler Could Not Deploy or Save

Summary

CPM Process Failed To Save/Deploy Object Event Handler

Content

I am not able to save object event handler using Process Designer. I uploaded PHP file and then try to save it after I test. It gives me error message "Limit Exceeded - Test Execution Must Complete in Less Than 157.000000 s"  I am sharing the screenshot.

What is the average time limit to execute/save object event handler for testing & for deploy ?

How can we increase their time limit to save/deploy object event handler. 

Thanks in Advance
