well guys... I'm so excited

after the test I mentioned, I finally clean installed my MacBook and wow... running on SSD with a clean install and using APFS partition (the one before was still Extended Journaled because it was installed on an hard drive)... well wow

cpu is even lower... never goes over 48% in all the project (while before had spikes around 55 and with sierra or the other high sierra versions I tried, it went to 60 and even 65% in some cases)... and:

I CAN PLAY IT WITH BUFFER AT 64!!

after 20 minutes of playing the mix stopping jumping around the project (I did all this quite fast to stress everything even more) and feeling like it was hardware... well I got a CPU error, but man, it was very well usable... and the CPU never went over 48% even there... (except for the spike)... and at 128 was like playing at 256 in the other tests

the other big difference between the tests I've done on the external HD and now is that before I hadn't 4 instances of Lexicon PCM working because I hadn't installed the plug in, now I have them working and the CPU has never been so low... also engaging and disengaging them takes like 1% of cpu...

Now, let's give you some reference so you understand why I'm so excited...

Pro Tools 10, one instance of Lexicon PCM was like 3/4% of CPU
This project in Pro Tools 10 was around 60% all the time going up to 80% with spikes sometimes, using it with buffer at 2048... here and there in a day of work I could get like 10 CPU spikes error

Pro Tools 2018.7 on High Sierra 10.13.6, 4 instances of Lexicon PCM are 1% but maybe not, I mean, you don't see the change except when you initiate them...
This project runs around 30% all the time... and sometimes goes up max to 48, other times goes as low as 17/20%

PLAYING IT WITH BUFFER AT 64!

Probably I'm feeling all this change because both Mavericks and Pro Tools 10 couldn't use efficiently the power of my mac... and now I've jumped in probably the most optimized OS/PT combo xD (but hey... the PT 10 and Mavericks combo I had, was perfectly optimized in itself, I mean, it worked better than pt 9 and 8 in my old mac pro, which was already super stable, so I'm not saying before it sucked, I'm just saying it wasn't optimized for my mac... in the end, I kept PT 10 just because it was a period of big changes both from Avid and Apple, now I felt it was a good time to do it and seems I was actually right xD)

WOW Seems I just bought a new computer for free xD
