Drew Gallatin explains why Netflix runs the development branch of FreeBSD in production on its CDN and how they track upstream changes.

We run FreeBSD-current on our CDN at Netflix. By running FreeBSD-current, we can find and fix bugs far more effectively than by running an older FreeBSD-stable branch. This talk describes our team, how we track FreeBSD-current, our contributions to FreeBSD, and some of the performance milestones we've hit. It will end with a description of a finding and fixing very interesting bug in upstream FreeBSD that caused a 20% performance regression. #OpenFest 2023 I Share Therefore I Am Website: openfest.org/ Facebook: facebook.com/OpenFestBulgaria Linkedin: linkedin.com/company/openfest-bulgaria/ (X) Twitter: twitter.com/OpenFestBG Instagram: instagram.com/OpenFestBulgaria Mastodon: mastodon.social/@openfest

On “FreeBSD 13.4-Release”

Your comment suggests that FreeBSD is a thing of a past and no longer capable of "quality networking", due to poor WiFi support. I can only agree with the poor WiFi support part. But WiFi is by no means something you can judge networking stack dedicated for servers. FreeBSD was never designed for consumer hardware networking. There were a few "desktop distros" but all have more or less died, and the few FreeBSD-based "storage distros" moved to Linux after FreeBSD changed its upstream for ZFS. And I'm saying this as someone who made a lot of effort to use FreeBSD on laptop over the years, and a current user of 15.0-CURRENT on ThinkPad. But FreeBSD was and is THE choice for high-bandwidth wire…

On “FreeBSD 14.4-Release Announcement”

> Or just run -current in production, like we do.0 If you develop, it's probably best to do that against current 1, but if I'm running a web, mail, file, database, etc , server there is IMHO very little advantage to doing so. Most folks aren't trying to push >400Gbps. 0 link to this video 1 link
