PS Bottlenecks
As with ILS, the performance of a server running PS depends on many factors. The most
important are:
•
the type of CPU in the system and its speed, the number of processors, and how much the
CPU is utilized
•
the type of network and its speed, the number of network interface cards (NICs), and the
device drivers for the NICs
•
the amount and type of memory in the system
•
the operating system
•
the web server software (IIS)
•
Personalization Software
•
the disk subsystem

The CPU utilization decreases as the number of users in the
UPD increases.
