This shit is fast as hell

-Upgrade codebase.

Here is the result of a benchmark done on a macbook pro m1.

@MacBook-Pro dart-server % wrk -t 6 -c 120 -d 10s --latency http://localhost:3000/
Running 10s test @ http://localhost:3000/
  6 threads and 120 connections

Just for reference, a node.js server with express running the same code:

@MacBook-Pro ~ % wrk -t 6 -c 120 -d 10s --latency http://localhost:3003/
Running 10s test @ http://localhost:3003/
  6 threads and 120 connections

Maybe it's time for dart servers to become more popular.
