Looking to dig deep? Try the Windows Performance Toolkit.
The Microsoft Edge team uses the Windows Performance Toolkit (WPT) for analyzing browser performance. WPT was created by the Windows team to conduct in-depth program performance analysis. It straddles the boundaries between website JavaScript and Microsoft Edge native code, allowing both to be viewed within the same tool. WPT can be used to:
- Measure CPU time taken for software to complete work
- Calculate the memory allocated by software
- Show the details of downloading files from remote servers
- Measure frame rate.
Here’s how to investigate website performance using the Windows Performance Toolkit.
