Bugzilla

To produce the data, first I recommend looking at the short video tutorial [here](https://learn.microsoft.com/en-us/windows-hardware/test/wpt/windows-performance-analyzer) from Microsoft to have an overview of the interface of Windows Performance Analyzer. Then, here are the steps to reproduce the graph:

1. Install Windows Performance Recorder and Windows Performance Analyzer from [the Windows ADK](https://learn.microsoft.com/en-us/windows-hardware/get-started/adk-install) for your version of Windows. For Windows 10 22H2 I think [this one](https://go.microsoft.com/fwlink/?linkid=2120254) should work.
2. Close as many open applications as possible to avoid noise in collecting the data.
3. Open Windows Performance Recorder and configure it as shown in attachment. Click `Start`.
4. Open Firefox and do the steps for which you want to analyze performance (e.g. load YouTube 5 times separated by intervals of 10 seconds).
5. Back in Windows Performance Recorder, click `Save`, click `Save`, click `Open in WPA`.
6. If Windows Performance Analyzer fails to load with error 0x80070032, install [Windows Performance Analyzer Preview from the Windows Store](https://apps.microsoft.com/store/detail/windows-performance-analyzer-preview/9N58QRW40DFW) and load the saved file from there to avoid the error (I personally have to do this).
7. In Windows Performance Analyzer, unroll `Computation`, drag and drop `CPU Usage (Precise)` to the empty portion of the window below under `Analysis`.
8. Under `Series`, navigate to the top. The processes are sorted based on which were the most active (hopefully, some `firefox.exe` processes and `MsMpEng.exe`). By using shift-clicking or control-clicking, select the most active `firefox.exe` processes and `MsMpEng.exe`, but not `Idle` (which is not a process). Then, right-click, `Disable`, `All but selection`.
9. Near, `Utilization by Process, Thread, Stack`, there is a `Select Chart Type` button. Click it and select `Stacked bars`, then move the cursor towards `Max`.
10. (Optional) Select the relevant portion of the graph, right-click, `Zoom`.
11. Use Snipping Tool to save and share the graph.

**Note: Please do not share the saved file publicly, as it may contain private information.**

Note: The graph should be enough assuming that it looks reasonably similar to mine. To reproduce the detailed activity of `MsMpEng.exe`, the steps are mostly the same, but you would need to set `Detail level` to `Verbose` when recording, then after all the previous steps you would click the `Trace` menu, click `Load Symbols`, wait a long time, and then progressively unroll the top-most entries under `MsMpEng.exe` like in the image I shared.
