mogul @ wrl.dec.com The Internet has experienced exponential growth in the use of the World-Wide Web, and rapid growth in the use of other Internet services such as VSENET news and electronic mail. These applications qualitatively differ from other network applications in the stresses they impose on busy server systems. Unlike traditional distributed systems, Internet servers must cope with huge user communities, short interactions, and long network latencies. Such servers require different kinds of operating system features to manage their resources effectively. 1

This paper presents a design capture system in which schematics are translated into a procedural netlist specification language. The circuit designer draws schematics with a standard structured graphics editor that knows nothing about netlists or schematics. The translator program analyzes the structured graphics output file and translates it into a procedural netlist specification. d i g i t a l Western Research Laboratory 250 University Avenue Palo Alto, California 94301 USA ii Table of Contents 1.

... This paper analyzes several programs and pro-gramming techniques to understand the performance implications of different pointer sizes. Many (but not all) programs show small but definite performance consequences, primarily due to cache and paging effects.
