CPU usage on Apple M1 is constant at 12% 2.0.6

Not mixing, Same problem isn't present on x86.

@soosr we are not doing any different on M1 in the code. Avalonia issue?

[soosr]

@nostitos Can you verify that you installed the ARM version on your M1? x86 can also run, but will be less effective.

[nostitos]

Yes it's the ARM version.

I can see the same on my arm macOS machine:

I ran WW from source code. So yes it appears there is something wrong. My guess would be that it is on the Avalonia side, but it's just a guess. If there is any idea what to test, I can test it as well. Btw, disabling GPU support in settings did not help me.

Seems no UI updates are happening (basically 0 FPS, zero layout or render invalidations - see graph and FPS overlay info):

My measurement was when I logged into my wallet. Could you check that as well please?

I did run profiler and seems like NBitcoin code is running in background thread:

@kiminuo when logged in (the same):

I did run profiler and seems like NBitcoin code is running in background thread:

It does. Its P2P code runs in a thread. I read that code a few times and I'm not aware why it should take significant amount of CPU but it's NBitcoin so everything is possible.

I actually waited a few minutes (like 3 I think) and on my machine it wend down from 40% to consistent 10%. However, it's weird that NBitcoin's code would take 10% of CPU on macOS arm64 and not on macOS x64 (my understanding of this issue).

There are some exceptions happening:

Definitely a lot of activity from many background threads:
