Operating System Barriers to Application
Performance
The impact the clients and servers
play in perceived network stability and application performance does not stop
with the connection to the network. Several factors exist that are commonly not
taken into consideration when looking at the performance of an application.
These factors include the operating system itself, which hosts the application,
and the hardware platform, which hosts the operating system and other I/O
functions.
Proper selection of the
application host server's hardware and operating system components improves the
overall performance and efficiency of the application. A poorly tuned
application server will have a negative effect on the application's performance
and functionality across the WAN.
Configuring a server to run
"optimally" requires a significant amount of research and can have a large
overall impact on application performance. This section describes operating
systems and offers guidance as to what aspects of the system should be examined
to enable better levels of application performance. The next section describes
the hardware.
