WASM benchmark

You can expericence this benchmark online at https://moonbitlang.github.io/moonbit-docs/benchmark/fibonacci/ or set it up at local following below instructions.

Fibonacci

This folder will use various programming languages to build Wasm, which will calculate the nth Fibonacci number for the benchmark.

Moonbit

Use Moonbit's playground or build tool to convert the following function to Wat:

func fib(num : Int) -> Int {
  fn aux(n, acc1, acc2) {
    match n {
      0 => acc1
      1 => acc2
      _ => aux(n - 1, acc2, acc1 + acc2)
    }
  }

  aux(num, 0, 1)
}

pub func test(n : Int, count : Int) -> Int {
  let mut i = 0
  let mut res = 0
  while i < count {
    res = fib(n)
    i = i + 1
  }
  res
}

Then use wat2wasm from the WebAssembly Binary Toolkit (WABT) to convert the WebAssembly text format (.wat) to the WebAssembly binary format (.wasm):

wat2wasm target/build/main/main.wat -o moonbit.wasm

Or you can just use the moonbit.wasm in current folder.

Start a web server with python3 -m http.server 8080, and we can now test the benchmark of Moonbit by browsing http://127.0.0.1:8080/

Golang

CAUTION: Do not use the wasm_exec.js in the current folder. Copy your own from GOROOT:

cp "$(go env GOROOT)/misc/wasm/wasm_exec.js" $PWD

Build golang.wasm

GOOS=js GOARCH=wasm go build -o golang.wasm ./main.go

Start a web server with python3 -m http.server 8080, and we can now test the benchmark of GO by browsing http://127.0.0.1:8080/

Rust

rustup target add wasm32-unknown-unknown
cd fib-rust
cargo build --target wasm32-unknown-unknown --release
mv target/wasm32-unknown-unknown/release/fib-rust.wasm ../rust.wasm
