One year of Roto, a compiled scripting language for Rust | Hacker News

Roto is already being used in real workloads, such as filtering updates in a BGP collector.

Maintainers say benchmarking is still limited, and there is more optimization work to do.

Current results show Roto beating Lua on naive Fibonacci and Iocaine, and roughly matching it on string-heavy code.

Its biggest weakness is list access, which is much slower because each access crosses into Rust and takes a mutex.
