Average CPU clock rate doubles every 18 months
Main memory data transfer speeds increase 10% every 18 months
Network node (end-system) operates at memory to I/O data transfer speeds
High-throughput networked applications forced to minimize number of operations involving main memory
Growth of CPU - Network performance mismatch
1997 - Jan. Intel Pentium MMX (150 - 233 MHz)
1997 - 2Q AMD K6 MMX (233 - 300 MHz)
1997 - 2Q Intel Pentium II (233 - 300 MHz)
1997 - 3Q Intel Deschutes (300 - 433 MHz)
PCI I/O bus 33 MHz x 32 b = 132 MB/s
