When you're talking about a box with 16-32 3 Ghz Cores and 128 GBs of  
ram with offloading NIC/CNA's that "software" is pretty speedy.   A  
single host running 3 vms can go  as high as 350,000 IOPs/sec from a  
storage perspective, and handle high PPS loads w/ 10GbE at line rate.   
Even "hardware" appliances like the ASA boot strap off what appears to  
be KVM and handle multiple contexts in software; and you really only  
need specialized ASIC's as part of the forwarding plane of high end  
routers.
