Important:
As with any laboratory benchmark, the performance metrics quoted in this
performance brief are idealized. In a production environment, these metrics
may be impacted by a variety of factors; for more information, refer to
Appendix B – SBC solution sizing .
HP determined that there were no disk or network bottlenecks in the test
environment.
Comparing scalability in the 32-bit environment
Scalability in the 32-bit HP SBC test environment was impacted by the particular processor model
being used, as shown in Figure 16.
Figure 16. More users were supported when the tested server was equipped with 8-core processors
Because the amount of memory consumed by chip-set drivers increases with core density, fewer free
System PTEs were available to the Model 6174 (12-core) processor-powered server at the start of the
test, which translated to support for 38% fewer Heavy Users.
