Notice

According to Bun 0.1.11 release note, seems like there are a performance different between Apple Silicon and x86_64 Linux.

On x86_64 Linux side, most benchmark catch up to KingWorld and Hono even surpass KingWorld in Get (/), however on Apple Silicon tells the different story up above.

I highly recommended testing this benchmark on your machine yourself.
