+# Encoding Benchmark
+
+Multiformats ships a number of base encoding algorithms. This module has no strong opinion
+on which is best, as long as it is case insensitive, so benchmark them to choose the fastest.
+
+At the time of writing `base8` is the fastest, followed other alorithms using `rfc4648` encoding
+internally in `multiformats` (e.g. `base16`, `base32`), and finally anything using `baseX` encoding.
+
+We choose base32upper which uses `rfc4648` because it has a longer alphabet so will shard better.
+
+## Usage
+
+```console
+$ npm i
+$ npm start
+
+> benchmarks-gc@1.0.0 start
+> npm run build && node dist/src/index.js
+
+
+> benchmarks-gc@1.0.0 build
