From PDF slides at https://people.freebsd.org/~gallatin/talks/OpenFest2023.pdf :

Netflix formerly ran FreeBSD-stable

  • "Merge [Netflix'] FreeBSD from FreeBSD-stable every few weeks."
  • "Moved to a new -stable branch every few years"
    -- "This sometimes took months"
  • "Upstreaming patches required porting them to -current"

Now, Netflix runs FreeBSD-current

  • "Merge upstream from FreeBSD-current every 3 weeks"
    -- "We notice & resolve new upstream bugs that impact us immediately"
    -- "Much easier to upstream code and collaborate with upstream developers"

Netflix FreeBSD Performance Milestones

  • "2017 -- First 100 Gb/s CDN server"
  • "2020 -- First 200 Gb/s CDN server"
  • "2021 -- First 400 Gb/s CDN server"
  • "2022 -- First 800 Gb/s CDN server"
  • "2023 -- First 100 Gb/s CDN server consuming only 100W of power"

Thanks to abhinavk for suggesting this very fun video!

I hope everyone gets the servers they want!

    This is amazing. FreeBSD is running super stable for me so I can understand you're running the current branche. To me it's like Debian in terms of stability but more current.

    FreeBSD has been around forever. Was popular long before Linux.

    The early history of BSD and Linux is a fascinating and intricate topic, but [...] :)

    according to Wiki FreeBSD started 2 years after Linux.....

    I'll continue what I started to write above (and was a reaction to what @Joseph said):

    The early history of BSD and Linux is a fascinating and intricate topic, but I'm not sure that it's quite accurate to say that FreeBSD "was popular long before Linux" :)

    In the early 90s, both BSD and Linux were both still very much niche-OSes, requiring a lot of know-how on the part of a prospective user to set up and use, and neither could have been said to be "popular" in anything like the ordinary sense of the word

    (Just to note that v1 of FreeBSD appeared in the fourth quarter of 1993, and v1 of the Linux kernel appeared in the first quarter of 1994)

    @someTom , where exactly do they say that FreeBSD started two years after Linux? This seems to me to be false

    (FreeBSD was more usable earlier than Linux, but they were both still very much niche-OSes)

    What wiki? That is just not correct.
    Also, FreeBSD is based on the original BSD that had it's first release in 1977 so trying to make it sound like Linux has been around longer then BSD is just absurd.

    Well, what wiki could it possibly be....

    https://en.wikipedia.org/wiki/FreeBSD
    Initial release 1 November 1993; 30 years ago

    https://en.wikipedia.org/wiki/Linux
    Initial release September 17, 1991; 32 years ago

    So "initial release" for Linux is 0.02 but for FreeBSD it's 1.0.
    You have to love wikipedia sometimes. :smile:

    In my comment above, I pointed out that v1 of the Linux kernel appeared in the first quarter of 1994

    The fewest of the few were using Linux before v1 of the kernel
