# 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:
By default, git credentials are not cached so you need to tell Git if you want to avoid having to provide them each time Github requires you to authenticate. On Mac, Git comes with an “osxkeychain” mode, which caches credentials in the secure keychain that’s attached to your system account.
You can tell Git you want to store credentials in the osxkeychain by running the following:-

Custom recipe to get OS X 10.11 El Capitan running from scratch, setup applications and developer environment. This is very similar (and currently mostly the same) as my 10.10 Yosemite setup recipe (as found on this gist https://gist.github.com/kevinelliott/0726211d17020a6abc1f). Note that I expect this to change significantly as I install El Capitan several times.
I use this gist to keep track of the important software and steps required to have a functioning system after a semi-annual fresh install. On average, I reinstall each computer from scratch every 6 months, and I do not perform upgrades between distros.
This keeps the system performing at top speeds, clean of trojans, spyware, and ensures that I maintain good organizational practices for my content and backups. I highly recommend this.
