## Benchmarks
> Disclaimer: Those benchmarks are probably far from real world usage scenarios and should not be taken too seriously before doing tests with your use-case in mind first.
If you feel any of the code available is wrong, please open a PR with a suggested fix.
The idea is just to hit some webpage doing a GET request to `/` and receiving the result body back.
For libraries that do not return the data as string, code to do that should be added, as is the case with Node.js `http.request`, `node-fetch` and `node-libcurl.Easy`.
A local server can be started with `yarn start-server`.
Benchmark can be started with `yarn start`.
