A. The basic rule or formula in the industry applicable to TCP/IP protocol is 1 MHZ of CPU for each megabit of data and allowing for application processing. This equates to a 1-GHZ CPU for a wire speed transfer in one direction or a 2-GHZ CPU for a bi-directional transfer in full-duplex mode when using the TCP/IP protocol stack. Using other protocols including UDP/IP or direct-IP can provide better performance with lower CPU utilization.
