Hello Maria,

This is very interesting news! Can you tell me more about this (maybe in 
a separate thread, to not pollute this one)? first few questions I do 
have:
1. Will this be done only in the 2.x branch, or also in the 1.6.x?
2. If you do use the Kernel protocol, is the entire Bird process still 
single threaded, or only the part regarding the Kernel protocol? So, 
calculating which route is best could still be multi threaded, but 
sending the end result to the kernel is single threaded
3. If you do use the Kernel protocol to send routes to the kernel, is 
there any alternative to get Bird fully multi threaded?

I run Bird on 4 routers, most of them have 8 cores, one of them even has 
12 cores, so I would love to be able to use all those cores for Bird! 
And I could even double the amount of cores if I would enable Hyper 
Threading again, but from a security point of view I don't want to do 
that.

Kind regards,
Cybertinus
