Chapter 6. Hardware Performance Issues

The hardware components of Unix systems may be the source of major performance issues. Processor speed is certainly not the only significant variable. Cache size and organization, TLB size and organization, bus structure and speed, I/O characteristics—all these and other variables are also very important.

This chapter will discuss some performance-related aspects of the major hardware units. Certain terms will be defined, and the architecture of several HP-UX systems will be presented in some detail. Topics are as follows:

  • Terminology

  • Processor Characteristics

  • Multi-Processing

  • Cache Memory Performance Issues

  • Main Memory Performance Issues

  • Physical and Virtual Address Space

  • I/O Performance Issues

  • PA-RISC Systems ...
