10 Mbit/second networks will be needed to handle the maximum transaction rate supported by either a ProLiant 2500 or ProLiant 7000. If a 10 Mbit is used, a bottleneck is possible, depending on the load one plans to generate in the environment.

PS performance measurements for both the ProLiant 2500 and 7000 have shown that they were capable of generating loads that fully utilize their CPUs.

Performance Analysis and Capacity
Planning for Microsoft Site Server on
Compaq ProLiant Servers
This white paper provides guidelines for planning the configuration of Compaq ProLiant
2500 and ProLiant 7000 computers that run Microsoft
°
Site Server Internet Locator
Server and Personalization System. In order to determine capacity planning guidelines,
system performance was measured under various load conditions.
