evelopers have been performance testing large
database applications for more than 20 years.
Up to now, they have focused primarily on
system-level testing of operating systems and
database management systems. However, just
because a machine, its operating system, and
its database system are fast does not mean that
an application using the database system will perform well.
Design flaws in the application or in the tuning parameters spe-
cific to the application's environment often result in serious per-
formance problems.
