This is where the system administrator has the task to best use the resources available without spending money on unnecessary upgrades that often have no real benefit.
Note: See Appendix A, ªSources of Drivers and Informationº on page147 for other sources of tuning information.
8.1 Performance Bottlenecks
There are some reasons for poor server performance that are difficult to measure or control. They include a poor choice of hardware, a badly written application and a network infrastructure that is badly designed and managed. This chapter focuses on the most important areas of concern when it comes to tuning and optimizing the available resources of your server, which includes the following:

Note
Always remember to document and measure any changes that you make, and if possible, not to make more than one change at a time. This way you will know which changes you made had the desired result and you will be able to replicate the knowledge you have gained in the process.
