A few points: - Polling and SMP are compatible in 6.1. In fact, they were compatible in earlier versions too; basically it's just the compile-time check that had to be "fixed." - You may have to adjust some parameters in the kern.polling sysctl tree - specifically, kern.polling.burst_max, kern.polling.each_burst and kern.polling.user_frac might need tweaking. - The polling feedback algorithm does not work very well if your workload is focused largely on per-packet tasks (such as routing or bridging). You'll find that there is still idle CPU time at the point you start dropping packets. I have some work in progress to address this, but it's not yet committed. - Polling's major advantage is the avoidance of livelock on UP systems, and not improved performance. What level of traffic are you putting through this box? Is it routing/ bridging, or an endpoint like a web server?
