Chapter 5. Performance TuningTo get the optimal performance from your NetWare server, you need to considerthe performance of both the hardware and the

LAN adapters and fast disk subsystems. In contrast, database servers typicallyneed fast processors (or multiple processors) and fast disk subsystems.

Systematic measurements of server performance employing adequate resolutiontypically produce a graph shaped like the one shown in Figure 140 on page 1
