Synthetic Module Benchmark with Web Bundles

Basic Usage

• Install Rust and Deno (optional) beforehand.
• See Make.zsh for example usages. The following is summary:

1. Checkout:

   git clone https://github.com/google/webbundle.git`
   

2. Generate the modules and the benchmarks.

   Example:

   cd webbundle/webbundle-bench
   cargo run --release -- --out out --depth 4 --branches 4
   

   See build() in Make.zsh.

3. Start webserver.

   Example:

   cd ../webbundle-server
   cargo build --release
   cd ../webbundle-bench
   RUST_LOG=error ../target/release/webbundle-server --port 8080
   

   See run_webserver() in Make.zsh.

4. Open http://localhost:8080/out/index.html in your browser, and click each benchmark.

5. (Optional) Run the benchmark using puppeteer for automation:

   deno run --allow-all ./run-bench.ts --port 8080
   

   See bench() in Make.zsh.

What's not implemented

webbundle-bench is inspired by js-modules-benchmark.

webbundle-bench is rewritten with Rust and Deno so we don't depend on Python and Node.js, and supports very minimum features which are necessary to benchmark Web Bundle loading performance.

webbundle-bench is missing many features at this point:

• Support modulepreload.
• Rules to generate modules.
• Specify the size of generated modules.
• Support other bundlers (e.g. rollup)
