My understanding was that Netflix liked FreeBSD for a few reasons, some of them more historical than others. * The networking stack was faster at the time * dtrace * async sendfile(2) https://lists.freebsd.org/pipermail/svn-src-head/2016-January/080924.html https://lists.freebsd.org/pipermail/svn-src-head/2016-Januar... Could they have contributed async sendfile(2) to linux as well? Probably. In 2024 these advantages seem to be moot: ebpf, io_uring, more maturity in the linux network stack plus FreeBSD losing more and more vendor support by the day .
