Performance improvements

[rracariu]

I recently watched this: https://youtu.be/DpDHPoStZZ8?si=988tsGnF4h7JkF3h - deno does not look good :(, or at least it could do a lot better.

Performance would likely be the one of the top selling points when choosing between bun, deno, and nodejs. Improving the performance should be a major ongoing effort, especially in setups as the ones described in the video.
