FreeBSD was used in 1999 to render The Matrix on 32 Pentium II boxes because the software in Linux Compatibility mode on FreeBSD was faster then natively on Linux, that is a fact:

FreeBSD can be several times faster then Linux when it comes to network stack:

But often Linux is faster, you just need to find benchmark that favorites one or another, both are fast in general.

Why on earth would you link to a Phoronix screenshot instead of the article that explains it?! Those results look suspicious enough[1] that I wanted to look it up. But of course I can't, and Google isn't helping me much.

Shame! Shame, shame, shame!

[1] Factor of 3+ differences not just between BSD and Linux but between otherwise very comparable linux distros. Something's weird with the setup there, like it's measuring default firewalling overhead or something and not kernel behavior.

I guess they have everything just set to default disto settings which likely in some cases include firewall while others don't. They also don't mention which NIC they are using, the motherboard has two different NICs (i218-LM & I210-AT).

Those benchmarks were run on machines with different processor clocks and different motherboard chipsets. The results are invalid.

This is something you come to expect if you've seen enough of what Phoronix publishes.
