The goal was to write a network driver in several languages. Nobody said anything about comparing memory management techniques, nor would the Swift implementation use a stack allocator anyways.

They would appreciate your contribution to fix the benchmark.

Apparently the ARC performance improvements announced at WWDC 2022 weren't needed.

I don’t think they would, considering they’ve already finished their study.

You could have your own repo to counterpost every time someone like me refers to that old study with tainted results.

I don't really have the skills to do an accurate comparison across many languages, and if I pick just three or four it's going to get nitpicked to death for being cherry-picked. Honestly, I generally think studies of this kind are mostly doomed to failure, or invariably converge to someone trying to encode x86 intrinsics in Rust.
