Why We Run FreeBSD current at Netflix - Drew Gallatin

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.

[@LuizPessol]

very good, thank you for sharing this presentation.

[@IVI-I]

Thanks for the detailed presentation. Compelling reasons to track current. Will need to look into the size of ARC performance hit with ZFS.

[@niacinsoupbowl]

Interesting talk, thanks.

[@Tb0ne212]

Great work! Thanks!

[@Felix-ve9hs]

Pretty amazing to think that almost all that runs on Netflix' servers is FreeBSD, Nginx and Bird.

What fascinates me as an example of how the group approaches their job is Netflix's willingness to let disks fail as opposed to investing in RAID. Focus on the customers' needs, not on sexy (expensive) technology--supports a very successful company. Lots of learning to do here.

Nice talk.

FreeBSD 🥰🥰🥰

[@faraday852]

great video, but doesn't really explain why they choose freebsd and not linux

[@Shahinc0]

he presented 04:00 UFS and ZFS file systems, in Linux can't find that Filesystems. and i think they are using for BSD license.

[@bonezed]

yes it seems like they chose FreeBSD partially due to politics, but I suspect it was also partly because FreeBSD is just different from mainstream

[@intreal]

I love FreeBSD so much, and I stuck with Linux on my home server because of a single piece of software which only runs in docker.

[@stefs1]

I had that too, but for that I Just did a little bhyve vm with Linux and Docker, and that solved my problems with missing Docker.
