+## Benchmark
+
+See the [benchmark results](results.md) to get an idea of the relative performance and
+compression efficiency of gzip, brotli and zstd in the current implementation.
+
 ## TODO
 
 - Add dictionary support to gzip and brotli (zstd already supports it)

+
+The benchmark names follow the format `Adapter/(body_size)/(encoder)/(level)/serial-*`.
+
+The first table lists time to compress the body with the specified encoder and level.
+
+The second table lists the size of the resulting compressed body.
