I would love it if someone could show a case where supernova just blows scserver out of the water
Generally, supernova will never be faster than multiple servers, but ideally it should get close. You would trade some performance for much increased flexibility.
(As a side note: you should also give each Group its own Bus and only sum into the hardware outputs after all Groups have completed. The idea is to keep all data access local and avoid synchronization to achieve better scalability. Again, this is not documented…)
I don’t have time right now to test your code, but I will do it later. If you’re interested in investigating this further, can you open a new thread?
