Dorico performance benchmarks?

In this thread, from almost 2 years ago, Daniel seems to be saying that Dorico does some things using multiple cores but in others it needs to be single-threaded. I tried limiting Dorico to a single core using Process Lasso and the performance hit was very substantial indeed.

He also acknowledged there were areas for improvement (hardware acceleration and, if I understand it correctly, general performance optimization), but they competed with multiple other things on the list. I would welcome and appreciate any updates or perspective on this.
