# Maximizing AV1 decoding speed: a modern 2022 encoding and decoding guide!

Hello. I've decided to share a lot more of my knowledge in public forums from now on, and to not divert any of my focus away from improving the world in a way that stays written in history.

This Gist is about discussing on how to improve AV1 decoding performance on 2 fronts: improving performance through more efficient decoding, and through decoding aware encoding.

Improving decoding performance through more efficient decoding.

Here are many tips on how to improve decoding performance on any machine:
