I know that @JorTurFer was interested in working on this, pending first profiling the Appset controller to see where the actual bottlenecks are (see #16594).

Yeah, I've it on my TODOs list, but currently there are too many things on my plate... 😢

I'm also running into this, I need to increase QPS and Burst. I will try to get a PR in this week
