It’s also what I understood. On Sun 02 Nov 2025 07:40:12 GMT, Mike Neo wrote:
And isn't it true that the speed of a single core is very important for routing daemons (control plane), but less so for packet forwarding (data plane), which can be parallelized between cores, especially in Linux?

As far as I understand it, BIRD 3 implements multithreading by allowing different protocol instances or routing tables to run on separate worker threads, but each individual bgp protocol instance itself still operates mostly in a single-threaded manner. Right?

Hi,
What's more important for a bird, the clock speed of a single processor core or the number of physical cores? For example, which is the better choice: 8x2.2 GHz or 4x3.8 GHz
Kind regards, Mike
I always prefer the performance per core. Even if bird3 is multi-threaded, you’ll always have some locks between the threads (eg. compute and actual next-hop from BGP using OSPF). And on pure routing, the higher the frequency is, the fastest the packet is routed.
