Anecdotally, Logic has consistently been the worst DAW in my testing, performance-wise, when it comes to hosting plugins. Maybe it's due to the AU format, but the de facto result is the same.

I run Ableton, FL, Pro Tools and Logic (mainly working in Ableton) and my goal is to record at 48k with a buffer length of 32 samples, with very light use of plugins. In my testing with the exact same plugins, Logic would consistently have buffer overflows every minute or so.

Ableton ran far more stable (especially in Rosetta), but PT was the only DAW to do it without hiccups. My initial guess is that the AAX plugin format is more tightly coupled to its internal processing, improving performance. But I was quite shocked to find out that Logic (Apple's own software) performed the worst.

Plugin development in general is a shitshow where most devs seemingly only do enough to get them barely working, so I'm not surprised most of them misbehave on ARM. It's a bit sad that we're two years into the Apple Silicon transition and performance still is so rocky.
