I accidentally made the fastest event system in the world — Orión
blog.ardis.dev
I wrote rt-events because I wanted a typed pub/sub in Rust. Then I benchmarked it against ten other languages and it came out ahead of monomorphized C++. The hot loop is six instructions. I cannot make it go any faster. Can you?

A ~200 LOC Rust crate benchmarked against ten other languages — came out ahead of a monomorphized C++ lib by ~4× at sub-fanout dispatch. Hot loop is six instructions. Can you make it faster?

    I have no clue about the different event systems specifically, but generally the less features you want out of something, the easier it is to make it fast. I would assume the others don’t need/want this extreme minimalism and trade it for something else.
