This repository contains several benchmark test cases found in the cases directory which are supposed to be used to benchmark the Wasmi WebAssembly interpreter.

Each benchmark test case can be compiled to WebAssembly, more precisely the wasm32-unknown-unknown target via the build_benches workspace binary. The compiled WebAssembly binaries are stored in the respective directory of each test case as out.wasm.

Wasmi uses these benchmarks by including them and their compiled artifacts as a Git submodule.

Build with

cargo run --package build_benches

This builds the benchmark .wasm files for all the Rust based benchmarks such as tiny_keccak, reverse_complement and regex_redux with proper optimizations and stores the results in their respective directories.

The scripts/lower-all-to-mvp.sh can be used to lower the out.wasm files or all cases to Wasm MVP (if possible) to make usage simpler for some Wasm runtimes.

./scripts/lower-all-to-mvp.sh

Use these scripts whenever a benchmark has changed or when a new Rust, LLVM or wasm-opt version has been released.
