Summary
Performancetuning and capacity planning are two vast disciplines that go hand inhand, and every system administrator should have a basic understandingof the concepts within each of them. These complex responsibilities aremuch easier to understand and manage if you categorize them accordingto the four major subsystems on a server: CPU, storage, memory, andnetworking. To manage performance tuning and capacity planning for yournetwork, you first must understand what metrics you must compile andhow to determine what they tell you about your particular operatingsystem. With this data, you can know what to expect from the normalbehavior of your systems. When abnormalities arise, you're then betterable to see what system components need to be tuned. You also recognizetrends that can help you plan for the future. This chapter merelyskimmed the surface of performance tuning and capacity planning,providing a high-level view of very complex topics; several bookslisted in Appendix A are dedicated to these subjects and can provide more details than you will ever need.
