Eliminate the CPU bottleneck in Linux with these optimization tools

Linux provides a rich set of tools to track the important statistics of a process and application's performance.

After your system-wide performance tools have determined which process is slowing down your Linux system, you will have to apply one of the numerous process-specific tools to figure out what that offending process is doing to slow performance and how to fix it. To understand an application's performance you have to measure how it is interacting with the operating system, CPU, and memory system. The book, Optimizing Linux Performance: A Hands-on Guide to Linux Performance Tools, written by Phillip Ezolt, explains how to measure and analyze the performance of the Linux operating system and the applications that run on it. The CPU-specific measurements explained in the chapter include:

• Determine whether an application's runtime is spent in the kernel or application
• Determine what library and system calls an application is making a how long they are taking
• Profile an application to figure out what source lines and functions are taking the longest time to complete

Do you have time to optimize the performance of your Linux systems or are you too busy dealing with users?
