FreeBSD has QoS available via PF and ALTQ. As for performance, Netflix chose FreeBSD for their CDN for the better network performance over linux. I do take your point about hardware support on consumer routers though - most of these are based on linux so its relatively easy to get linux based *wrt installed on them

Stop thinking like QoS has a singular meaning. ALTQ provides the aforementioned '90s-era inferior QoS techniques, and it isn't even available on FreeBSD without recompiling the kernel. The dummynet module is a little more modern, and in February patches appeared implementing the CoDel and FQ-CoDel AQMs that Linux has had for four years.

afaik netbsd npf is the first bsd packet filter to support multiple cores, and its far from backed.

big business usually use their own network stack as stock bsd is at most suited for soho workloads
