Is BIRD on BSD a second class citizen?

[k simon]

Hello,
FreeBSD does not support MPLS and VRF, but it support ECMP by recompile kernel with “options RADIX_MPATH”, and quagga/frr have supported it for few years . Not much of  people use MPLS on freeware. BSDer always use multi routing tables which FB called FIB to replace VRF. It’s limited, but it’s usable to most people.
For the past years, FB has refactored the routing subsystem aimed to reduce contentions on SMP systems, [1][2]. Linux is  winner, but now FB can archive up to 10MPPS forward rate on one 8-core x86 server.  It’s enough to many people, right ?
And FB has an awesome feature called vimage/vnet, it’s similar to LXC on Linux with different implementation. We run serval bird/frr instance in different vnet jail on one host, and run serval on another host for hot backup or load sharing,  each instance is independent with ~5% performance loss.
