Note that this test did not involve full BGP. Given the problems that  
used to occur on some name
brand routers when BGP took up too much CPU, I would be careful  
extrapolating these results if you
are planning on running full BGP. As the paper itself says,
" In a real-world situation the device might be running BGP, with a full
routing table. This will surely affect the performance of the device."
