Gigabit/SMP performance problem
Quoted 4 lines · Avery Fay
can probably handle all of the interrupts. Really the issue I'm trying to solve is not routing performance, but rather the fact that SMP routing performance is worse while using twice the cpu time (2 cpu's at around 95% vs. 1 at around 95%).
Please forgive me if this is a silly suggestion, but are you sure this is a real 95% utilisation in the 2 CPU case. I think some versions of top show 0..200% for the 2 CPU case, and therefore 95% utilisation is represents a real CPU utilisation of 47.5%
