Note that UBNT claims line rate throughput and provides proof via a commissioned Tolly report (no idea on their legitimacy).
The fbsd image yields ~250mbps between two gigabit hosts.
I've been eyeing one of these for a while and putting fbsd on it interests me, but not if it means a huge peformance drop (even if I wouldn't really miss it).
Assuming UBNT is correct and the device supports line-rate throughput, I don't think there's any reason why FreeBSD couldn't easily support that.
The freebsd-mips mailing list already has a few threads discussing this; if you want to know why the router isn't achieving line-rate speeds "out of the box", you'll probably get the best answer there (and maybe even someone who knows how to fix the problem):
To get any decent performance you have to use a horrible binary blob kernel module that offloads (certain very specific use cases) to hardware acceleration. See this post for more info: https://news.ycombinator.com/item?id=7282258
