Those numbers are on a Series 2 and tested after a reboot and waiting for 10 minutes or so for the OS to settle down.
I have noticed that launches of simple apps like settings, stopwatch, alarm, etc are done in just under 2 seconds whereas it was around 4 seconds on watchOS 4.0 and prior. Also would be interested in any observations of watchOS 4.1. can you elaborate further on the relative performance of the the 3 different watch silicon generations? Since you are paying attention to rendering performance, your perspective would be interesting.
Wow, that's a very nice writeup of the new release.
