225kpps * 1500 bytes = 2.7Gbps.
225kpps * 64 bytes = 115Mbps.

Or to put it another way, line rate on a GigE w/small packets is 
1.488Mpps, of which 225kpps is only ~15%. As with any software router, 
the limitation is mostly in the lookups/sec, not the volume of traffic. 
If you don't care about high pps or predictable performance, or if you 
only have a 100Mbps uplink feeding the thing in the first place, a sw 
router may be fine. But keep in mind that a $100 linux box can put out 
225kpps with one NIC tied behind its back, so you'd best hope you never 
get a DoS attack.
