I run a firewall that sustains anywhere from 10-50 megabits/sec on it on a pair of R210 machines. Both are running 4.9-RELEASE amd64 MP just fine. I did tweak some stuff in the BIOS, namely, I disabled virtualization and set the IRQs to default in it. Though I believe the work in the area of interrupts has been improved in -current. 5.0 should run even more smoothly. I had no problems with these R210s except for when pfsync was up but one of the interfaces on the CARP backup had no link. The master CARP machine sort of fell over, but I was unable to get a trace. I've had no problems since, however.
