"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. We'll concentrate on
I/O performance because it is the area most commonly addressed by
IT managers and administrators. 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."
