This chapter contains an example of how to use the Linux performance tools to find and fix a performance problem that affects the entire system rather than a specific application.
After reading this chapter, you should be able to
Track down which individual process is causing the system to slow down.
Use strace to investigate the performance behavior of a process that is not CPU-bound.
Use strace to investigate how an application is interacting with the Linux kernel.
Submit bug reports that describe a performance problem so that an author or maintainer has enough information to fix the problem.
