Doesn't work for every case, but I think for a lot of cases nowadays, if you are using an interpreter and its slow, you should just generate web assembly. Libraries like walrus for rust make this pretty easy to do, and wasmtime provides a serviceable standalone runtime. For my little language, recursive fib(40) executes in firefox with wasm in about 600ms. My interpreter basically can't finish it.
