I think I might have been the first person who reported this in 2019: https://github.com/rust-lang/rust/issues/59087 https://github.com/rust-lang/rust/issues/59087 It’s a pretty interesting problem. While everyone assumed that futures are lightweight and thereby more efficient than threads, there’s a couple interesting performance gotchas like this one that apply for certain libraries and applications. Due to those I’m still m curious for how many applications the async model is actually a net win or a net loss. Too bad we don’t have time to implement all applications in both ways to gather more data.
