> I mean... 300 tracks? You're basically testing the DAW's thread management at that point, not the CPU as it would be used. Any realistic test is going to have more tracks than there are CPU cores, so thread management would seem to be an unavoidable aspect of the test. The test results were in the 60–100 track range, not 300, so not really as excessive as you are claiming. And while testing with too many tracks could certainly be problematic for introducing excessive context switching overhead, the problematic behavior that was actually revealed is much more serious and less subtle and applies to any scenario with more than 5–8 threads.
