Subject: Re: [PATCH v3 00/35] Per-VMA locks


Here are some measurements from a Pixel 7 Pro that´s running a kernel either with the Per-VMA locks patchset or without. 
If there´s interest I can provide results of other specific apps as well.

Results are from consecutive cold app launches issued with "am start" command spawning the main activity of Slack Android app.

There´s quite a noticeable improvement, as can be seen in the graph. The results were reproducible. 

If you have any questions feel free to ask.
