This commit starts to add a page of microbenchmarks for wasm-bindgen which we can hopefully track and compare over time. Right now it's primarily focused on data collection, making it easy to collect data across a number of benchmarks for comparison. It doesn't currently do much in the way of actually comparing the results for you (aka drawing pretty graphs), so let's left for a future step. It's hoped though that we can use this to track performance improvements as well as ensuring that they work over time!

# Microbenchmarks for `wasm-bindgen`
|
|
|
|
This folder houses a number of microbenchmarks for `wasm-bindgen`. These, like
|
|
all microbenchmarks, should be taken with a grain of salt. They are intended to
|
|
help developers understand changes over time, but they are not intended to be a
|
|
performance suite for WebAssembly for Rust.

## Building and Running
|
|
|
|
First, copy the benchmarks to a temporary directory:
|
|
|
|
```
|
|
$ cp ./benchmarks /some/other/directory
|
|
```
|
|
|
|
Next, `cd` into that directory and execute:
|
|
|
|
```
|
|
$ wasm-pack build --target web
|
|
```
|
|
|
|
Next, use your favorite static file server to host the current directory. For
|
|
example using the [`https` crate](https://crates.io/crates/https):
|
|
|
|
```
|
|
$ http
|
|
```
|
|
|
|
Then open up a web browser and view http://localhost:8000, for example.
|
|
|
|
You should be presented a page with lots of `(run)` links, where when you click
|
|
them it will execute the benchmark and then display the result.
|
|
|
|
## Benchmark Architecture
|
|
|
|
Currently benchmarks are pretty bare bones. They just use benchmark.js to
|
|
generate statistics which are then rendered to the screen. Benchmarks are listed
|
|
one-by-one in `index.html` where a `td` exists for each benchmark. In `index.js`
|
|
each of the `td`'s `id` properties are hooked up to an actual function to
|
|
benchmark, depending on what's being benchmarked.
|
|
|
|
Relevant files are:
|
|
|
|
* `index.html` - the page showing all benchmarks
|
|
* `index.js` - the driver JS for all benchmarks
|
|
* `globals.js` - global JS functions imported by all other benchmarks
|
|
* `js-bencharks.js` - the JS functions that we're benchmarking
|
|
* `src/lib.rs` - the Rust/`wasm-bindgen` functions we're benchmarking
|
|
* `raw.wast`/`raw.wasm` - a raw handwritten WebAssembly file used in some
|
|
benchmarks. A compiled version of this is checked into the repository.
