There are many reasons why a system might appear to be running slowly, and trying to determine the cause and remedy can be time consuming. This section describes the tests that can be run to locate where possible problems exist and provides instructions on what to do to help improve performance.
The key items that can affect system performance can be summarized as follows:
-
Server hardware (such as speed, memory, distributed processing)
-
Server OS configuration (for instance, 32 or 64-bit, settings)
-
Database resources and tuning
-
Network performance
-
Client hardware
-
