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)

The SO_REUSEPORT socket option

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).
