This is a comparison a few different rust async executors against each other to see how they handle many (relatively uniform) tasks.
The tasks are 2990 unique pathfinding tasks using polyanya.
System tested on: Windows 11, AMD 5900x:
| Executor | runtime |
|---|---|
| switchyard | 3699.8 ms |
| smolscale | 231.77 ms |
| bevy_tasks | 406.98 ms |
| tokio | 300.87 ms |
| rayon | 205.48 ms |
| singlethreaded | 3111.5 ms |
Run cargo --bench to get criterion benchmarks.
cargo run --release is faster, but much less accurate and doesn't keep track of previous runs.
