The Application Performance Management (APM) SuiteApp enables you to see and manage the performance of your NetSuite customizations and business-critical operations.

Analyzing Scripts:

1. We can adjust date ranges.

2. Follow the navigation : Customization> Performance> Suitescript Analysis

3. Then we can select individual scripts and analyze the performance based on the execution time etc. See the below graph we can also see the total time at the right of the screen. We can also hover through the bar graphs to see the execution time on each instance.
4. We can choose only one script at a time. So comparing more than one script is not possible.
5. We can see metrics about the individual entry points of each script
6. These are the features of this tool.
