It uses a Cavium Octeon processor which does have dedicated HW packet proce=
ssing. A moderate number of prefixes won't slow it down doing vanilla for=
warding, not sure about 2 million though... I believe they have recently o=
ptimized some of the FW stuff to take advantage of the HW as well. =20
Layering services like FW, NAT, and tunneling definitely drops the packet r=
ate significantly, but it is still capable of 100+Mbps at IMIX packet sizes=

I think there are a couple of in depth tests out there.
In my experience the ERL works really well for a $99 device.=20

Does anyone have any practical experience with the EdgeRouter with a
largish number of prefixes?
http://dl.ubnt.com/datasheets/edgemax/EdgeRouter_DS.pdf
The "2 million+ packets per second" leads me to believe that this is
merely a highly optimized software based router, but under "Hardware
Specs" it specifically says "hardware acceleration for packet=20
processing".
I have no idea what's being accelerated since the "layer 3 forwarding
performance" specs for the FR-8 are 2Mpps (an 800MHz CPU) and the=20
FRPro-8 are 2.4Mpps (1GHz) which suggests software lookup.
Do these things suffer if you load them down with a full table? Or
a handful of firewall rules?
