A question for both you and the parent:
If you are heavily performance and memory constrained, why are you using a language that gives you relatively little control over allocations?
In my case it was a choice made long ago, when the exact consequences weren’t fully apparent. I don’t think when making those initial decisions people understood how important low memory usage would turn out to be, or that Go would be an obstacle to that. And we’ve got so much code in Go at this point it would be a huge lift to switch languages. The language does have some nice features that make things easier. It’s just in certain portions of the code, in the really hot loops.
