Integrate with industry-standard benchmarks

[VinnyVicious]

I think seastar could benefit a lot from featuring on popular industry-standard benchmarks, such as:

• https://web-frameworks-benchmark.netlify.app/
• https://www.techempower.com/benchmarks/#hw=ph&test=fortune&section=data-r22

I know, from experience, that Seastar is much faster than drogon. What do you guys think should be a good minimal example of Seastar's superiority? Also, any tips on how to connect to postgres in a minimal way so it only does the minimum to satisfy TechEmpower?

I would be glad to add it to the benchmarks, but would love the opinion from the community so I only push code that is optimal for Seastar.
