(mysql.info)MySQL Optimization

Optimization is a complicated task because it ultimately requires
understanding of the whole system. While it may be possible to do some
local optimizations with small knowledge of your system or application,
the more optimal you want your system to become the more you will have
to know about it.

This chapter will try to explain and give some examples of different
ways to optimize MySQL.  Remember, however, that there are always some
(increasingly harder) additional ways to make the system even faster.
