there was a time when freebsd's networking stack was pretty trendy for use in high performance networking settings. it was frequently used to implement things like software load balancers. quite possibly because of its (pre-linux-cfq) superior resource scheduling. there was also a time before it was trendy to complain about the GIL in python where SMP in freebsd suffered from the BKL. only one processor could be in the kernel at a time.
