 I gave up giving my projects original names a long time ago, so now I just use
 the names of my friends ;p

+## Benchmarking
+
+I benchmark this tool using the [`wrk2`](https://github.com/giltene/wrk2)
+utility. I've provided two Lua scripts to aid with this. To bench publishing
+redirects, use the following:
+
+```sh
+wrk2 -s bench/post.lua -t 10 -R 10k -d30s -c32 http://localhost:18080
+```
+
+And to bench GET requests:
+
+```sh
+wrk2 -s bench/get.lua -t 10 -R 25k -d30s -c32 http://localhost:18080
+```
+
+Of course you're free to change the parameters, but the provided Lua files
+generate URLs that can be used in the benchmark.
