I created a benchmark suite for the `tfb`, see [here](https://github.com/TechEmpower/FrameworkBenchmarks/tree/master/frameworks/C%2B%2B/drogon) for details.
I also created a test suite for another web frameworks benchmark repository, see [here](https://github.com/the-benchmarker/web-frameworks/tree/master/cpp/drogon), in this project, drogon is used as a sub-module (locally include in the project).
