Is there side effect running intel-based app in M1/M2?

[Isamilis]

Hi everyone,

I still have to run few non-native apps on my M2 mba / Monterey. Is there any impact or side effect using them intensively? I heard in early days (Big Sur?) it creates large swap due to conversion overhead. Is this still true?

Thanks!

There is the overhead being discussed on this thread https://forums.macrumors.com/thread...db.2391222/page-2?post=32204989#post-32204989. But, that disk consumption happens when the app is first used, not on repeated uses.

Are you able to find any links about swap overhead? I'm interested to read about it.

I'd want to see compelling evidence for the 'swap' claim. Running Intel code should simply mean that the app is not as fast as it could be -- I've seen a 10% performance hit running an app in Rosetta. There will be a bit of disk space used for the translated runtime.

Thanks for your reply. I remember I read old thread discussing what trigger the excessive swap in M1 machine, where one of speculation is due to running apps under rosetta. Unfortunately, I couldn't find the thread.
