At least from a quick glance in the polling(4) manpage I cannot see that bge
is among the supported devices.
If you want to use polling, I suppose that you need to enable it via ifconfig,
too:
polling
If the driver has user-configurable polling(4) support, select
the polling mode on the interface.

Several wild guesses from my own experiences here:
- SMP + networking in 5.x does not work too well, using em(4) I experienced
VERY poor performance (only ~5MB/s over a Gbit link)
- Try upgrading to 6.x (as others have already suggested). I experienced all
kind of weird problems with 5.x, and although there is no proof that the
problems were actually related to 5.x, 6.x seems to work better.
- What's the value of nmbclusters? Have you checked netstat -m? Do you see
memory requests for network memory denied?
- 50% interrupts on such a fast machine is quite high. I currently experience
about 30% interrupt load using two em(4) cards, shaping for about ~2000
clients on a 3.8GHz Xeon.
Kind regards
