Policies for Custom Form on the Web Interface


So I have been "handed" a website that uses the Active Roles Server software and I was curious on if anybody could shed some light on how policies are incorporated within a custom web form. Our company has created a form that allows admins to create new users on the front end, and I see on the back end (the ARS console) that it runs various scripts and validations of input fields that the admin fills out for this newly created user. I guess my dumb question is how would I determine when these scripts/validations are being run? Where are some good places to look for trying to figure out what this form does?

My main concern being is that I am not sure that for every step in this form, the scripts are running in which causes performance issues between the tabs. (This custom form is really slow and I have been tasked to try to speed things up.)

Thank you kindly.
