Speaking as somebody who works on the FreeBSD kernel at Netflix, the whole article is kind of nonsensical. We don't use FreeBSD because of "latency". We serve clients over https that could be tens or hundreds of ms away using the kernel TCP stack. The folks who care about latency are high frequency traders, who care about every nanosecond. They tend to use userspace / hardware offloaded solutions and do things like busy-waiting for messages.
