I am running with a level of 1 currently but it would be nice to have 0 with quick start for some of the apps I agree graal would be the ideal but library support is an issue as far as I am aware although not tested on my projects

it seems like graal or using node as a backend are probably good options for startup time

I am curious how you are profiling are you doing that on cloud run or just locally using some profiling tool ?

Have just been profiling locally. I don't know if cloud trace can provide any statistics out of the box but the docs seem to indicate that it can.
