Figure 5. Relative Score performance of Pentium Pro/166.
. .
. .
This data illustrates the increased power of the Pentium Pro processor with 32-bit Windows
. .
. .
NT applications.
. .
. .
Note that this system uses the PCI SMART-2 Array Controller rather than the EISA SMART
. .
Array Controller as in previous tests. Some of the performance benefit here could be
. .
. .
attributed to better performance of the disk subsystem.
. .
. .
The server is less quick to consume processor resource. 1000 users can easily be supported
. .
with subsecond response time.
. .
. .
. .
Interestingly, there is no real apparent bottleneck in the server hardware itself. However, the
. .
gradual slowdown trend continues as with Pentium/133 and Pentium/166. This could be due
. .
. . to the Exchange software itself, although it is faster overall than the Pentium-class processor
. .
subsystems.
. .
. .
This data implies that the system would be able to handle other tasks besides the email and
. .
. .
public folder tasks in the LoadSim user profile. For example, the second CPU would likely be
. .
used more effectively if a gateway or some other Exchange process is added to the system.

Single CPU Processor Subsystem Comparison

Figures 6 and 7 show a comparison of the performance of the different processor subsystems
. .
examined. Figure 6 compares single CPU configurations. Figure 7 compares dual CPU
. .
. . configurations.
