Check a User Path taking more time to validate

I have around 12 user path (each user path will have at least 2-3 web service calls).

When I am trying to check user path, it is taking longer time. Typically it is taking around 1 min 30 seconds every time.

Though I have more than 10 User Paths, I am trying to validate only one at a time.

Also I do not have any think time or pacing and disabled time taking settings in the Advanced (User Path).

I have increased the memory usage of my localhost LG. But still the time is taking longer than usual.

This issue I never faced and no changes has been done.Only change I had done is: added Dynatrace User path to my project.

Version : 7.2.1
Project settings: XML
