You shouldn't worry too much about quagga performance (quagga's CPU  
usage won't be a limiting factor, the main limit will be how fast  
your machine can forward packets), and one of the main advantages of  
using quagga is that memory for your typical Linux system is a LOT  
cheaper than Cisco's.

For your reference: I just checked one of our routers, the "zebra"  
process is using 50 MB, and "bgpd" is using about 100. We receive two  
feeds of about 220k routes. So for the current size of the routing  
table I'd guess you need at least 350 MB of memory (6x 50 MB for  
bgpd, and 50 for zebra).
