However, at least two 10 Mbit/second networks will be needed to handle the maximum transaction rate supported by either a ProLiant 2500 or ProLiant 7000 - HP ProLiant 2500 | Performance Analysis and Capacity Planning for Microsoft Site - Page 21

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.
