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. https://docs.google.com/spreadsheets/d/1ktujfcyDmIJoQMWsoizGIE-0A_jMS9VMw_seehUY9s0/edit?usp=sharing 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.
