I am connecting into an M1 macbook (Sonoma) from a 2019 iMac (Sonoma, 64GB, i9, Radeon 570x 4GB) utilizing Apple Display screen Sharing.
Particularly when viewing Chrome / Electron based mostly purposes, the iMac’s followers begin spinning at full rev, and I discover 100% or extra CPU utilization by the Display screen sharing app (not globally as proven on the Exercise Monitor graph). I’ve observed that it occurs when there may be mouse or keyboard exercise; as quickly as I change out of the Display screen Sharing app on the iMac, the CPU utilization will get right down to regular, even after I maintain the Display screen Sharing window seen, with all of the macbook’s UI updates happening.
Certain, it is summer time, the 2019 iMac is not a teen or a graphics dragon, however:
- if I join into the exact same M1 from my 2015 iMac (Mojave), I haven’t got this drawback, the followers spin up at times, however nothing noticeable;
- it is not Sonoma particular, as a result of I haven’t got issues connecting from my M2 macbook (Sonoma, ARD basic mode, the superior is just too buggy) both (however it may be Intel-Sonoma particular);
- it truly is sure to mouse / keyboard exercise, and it actually is dependent upon the app working on the M1, Chrome + Electron apps being the worst offenders.
My answer up to now has been to throw cpulimit with a 75% restrict at Display screen Sharing. It solves the fan noise, however Display screen Sharing begins stuttering rather a lot with some Electron apps (not all). Then I cease utilizing the mouse or keyboard, and it will get again to working easily.
Does anybody have any pointers?
