Default Re: "High" Sierra Better For 2018 Than "Plain" Sierra"?

So this thread got me curious I realize everybody's workflows are very different
But most of my virtual instrument recording is one track at a time
I have tried recording a drum kit like the big boys and play all the drums to different tracks at the same time but frankly being a guitarist I suck at it .
I have recorded PT' Boom to different tracks a number of times

Any way

I just ran some tests at 16-44, 24-44, and 24-88 sample and bit rates
At 32- 64 and 256 Buffer .

I was using the PT Bundled Mini Grand piano and AIR Dynamic Delay
Tracks were record armed I would play notes with my keyboard and record

At 24 -88 at 64 buffer I could run 5 tracks over that I started getting spikes and ocasional overload system squeak noises

At 24 -44 at 32 buffer I could run 12 tracks with no spikes @ about 31% total at idle but it would go up to 80 -95% when playing notes.
At 13 tracks the system usage total meter would spike for a few seconds but drop and I could play and record.
At 14 tracks the total was up about 55% and it redlined a couple times but played fine . at 15 it started squeaking

At 16 -44 at 32 buffer it played 20 tracks I gave up there
