First of all, thank you for the microprofiler dumps. We can only make things better together.
As far as the platforms and codebases are concerned, I can relate to the frustration; I’ve run into this multiple times during my professional experience and the two avenues to take were: either improve the dev environment or the codebase. Often both of these approaches are needed.
As far as Roblox Studio is concerned, we’re currently working on improving the auto recovery that you mentioned. The fact that it saves even with the setting disabled is not acceptable.
There is also a workstream to speed up serialization / deserialization.
Our main focus is stability and performance right now as mentioned here and the improvements will keep coming.
