"Everywhere you look someone is trying to sell you a Linux- based solution, touting some superior capability or other inherent attribute of this popular open-source operating system. It is claimed that Linux is more robust, more secure and more efficient in its use of hardware resources compared with the market leader in Intel-based systems, Microsoft Windows NT. That's all fine and good, but how do you know Linux is using your hardware to its fullest? Here are tips on manipulating some of Linux's performance-tuning parameters to make the system scream."
"You'll face two types of performance bottlenecks when designing a system: input/output and program execution.

Most improvements in the arena of program execution must be discovered and implemented by the programmer, not the IT department...."
"If you're running Linux as a Web server or a file server, your tuning priorities are going to be different than if you're running it as a desktop. On a server, you tend to maximize speed and responsiveness at the cost of "space" (RAM and disk space). While the Linux desktop market does exist, maximizing Linux's use as a server is our goal here."
