FreeBSD gigabit bridge/router/nic/kernel issue and more

Can anyone tell me about performance issues re. freebsd
in filtering bridge configuration, compared to router
configuration? The filtering will take place between 
two ethernet gigabit interfaces. Also, what kind of ethernet
fiber SX gigabit interface is recommended for production
use? I need to continue maintaing high uptime and stability
is primary concern, also it need to perform well and of course
the driver must work well.

How many NMBCLUSTERS do I need for a bussy 1 gbit ethernet
filtering bridge or router? Other kernel issues to keep in mind?

I use ipf for ip filtering. I was also wondering if there exist
any dual fiber gigabit ethernet cards (two fiber-pairs on one
card) in order to save pci slot space.

I will be grateful for any hints or comments.
