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. -- Alarig
