ok it seems like we find the issue. The new optimization was completely disabled in nebula3 and nebula3 pro. It was working for client server only, at least on pc side. It explains the difference in performances among different users. Now: 1.3.7 without this optimisation is SLOWER and a LOT slower than previous version because we added tons of code for making it safer. So you had a slower version, not faster. Adding this optimization you get something in the same ballpark as before, and in most of cases a lot faster.
Am i glitching or 1.3.710 is +30% CPU efficient as 1.3.708 on Mac? O____o Just loaded project on which i'm working and my CPU load (with 30+ instances of Nebula + around 60 other plugs) is only 25%.. Is there some new optimizations with 710 or it's my macbook pro joking around?..
