 The author of Zstd also wrote lz4. Zstd is intended to occupy a speed/ratio
 level similar to what zlib currently provides.  In our tests, the can always

+You can run the benchmarks against your own payloads by using the Go benchmarks tool.
+Just export your payload filepath as the `PAYLOAD` environment variable and run the benchmarks:

+go test -bench .
