I’m not really up on what goes on with prioritising threads but it seems to have squeezed a little more performance in my tests.
As noted in that thread what I am listening for is clean audio without clicks caused by CPU spikes due to other processes on my iMac. This is a fairly marginal business and the error here is probably -1/-2 VCO-1s.
The iMac has had as much cruft stopped on it as I can so it probably doesn’t represent real world usage of most people’s computers.
Forgive my ignorance but is thread boosting/prioritising more likely to have a greater effect when Rack is competing against other processes that are using significant CPU as opposed to when it is competing with daeamons or other process with <1% CPU ?
