MG2 with AUM on 2018 iPad Pro 12" - issues

I reset my iPad - vol up, vol down, home button long press sequence. Created same config - I now have less DSP load - for my “big” AUM setup it’s around 75% on 64 buffer, and around 50% with 128 buffer size. I believe 128 is a reasonable compromise, if it works stable. Does MG use multi core or a single core? Thanks!

MG itself is singlecore.
To avoid misunderstandings here: certainly If you run AUM lower than 256 on an ipad, you need to shut up all apps you currently have opened and dont need. that means: double click home button, swipe all apps you dont need up out of the screen.
