| This chapter contains an example of how to use the Linux performance tools to find and fix performance problems in a CPU-bound application. After reading this chapter, you should be able to Figure out which source lines are using all the CPU in a CPU-bound application. Use ltrace and oprofile to figure out how often an application is calling various internal and external functions. Look for patterns in the applications source, and search online for information about how an application behaves and possible solutions. Use this chapter as a template for tracking down a CPU-related performance problem.
