In other news, what Linux comes up is setting standards, because there have not been any standards before :)

Hey, Linux is THE trendsetter here. Linux hackers and organizations behind its development are certainly not going to wait for some standards body like POSIX, IETF, or whoever to get off their keisters to address this issue! Especially when we're...

...dealing with applications that accept 40,000 connections per second. :)

Well, again, it was in BSD first. Credit where it's due.

But generally, Unix "standards" have always trailed implementations. It's just that now Linux and BSD are in reality the primary Unix implementations.

(cue screams about which is the real unix)

DragonFly BSD has implemented SO_REUSEPORT since July 2013 too; http://lists.dragonflybsd.org/pipermail/users/2013-July/0... has some very interesting performance numbers.

SO_REUSEPORT naturally aligns with networks stacks parallelized like DFly's/Solaris's (hash connection state early, map & fanout to a fixed CPU per connection, no locking till you hit socket buffer layer).
