What is Performance Tuning?

Performance Overview 1-3

■ Wait Time

■ Critical Resources

■ Effects of Excessive Demand

■ Adjustments to Relieve Problems

Response Time

Because response time equals service time plus wait time, you can increase

performance in this area by:

■ Reducing wait time

■ Reducing service time

Figure 1–1 illustrates ten independent tasks competing for a single resource.

Figure 1–1 Sequential processing of independent tasks

In this example, only task 1 runs without waiting. Task 2 must wait until task 1 has

completed; task 3 must wait until tasks 1 and 2 have completed, and so on.

(Although the figure shows the independent tasks as the same size, the size of the

tasks will vary.)
