> Even if that’s true then it remains a failing of the Linux ecosystem that they were unable to understand how to configure it correctly or that the defaults did not work as well as the FreeBSD ones. Or alternatively they just did not put the time in. No defaults cover all use cases, almost all software I have ever used in high load applications needed some tuning, this includes Solaris, MySQL and MongoDB among others. > But I don’t think it’s the case as they’ve put a lot of work into hiring some of the brightest minds in OS development, including Brendan Gregg AFAIK Netflix has used FreeBSD since 2012[1] and Brendan Gregg only started working at FreeBSD in 2014[2]. So not sure this really shows they knew what they were doing when they made the choice to go with FreeBSD. It could be they did but I still would like to something more than just Netflix's choice to back the claim up. Many more companies choose Linux.
