Processor use

In the performance testing, the IBM Lotus Domino server processor time remained below 15%, which is well below
the upper threshold of 75% that should not be exceeded on an IBM Lotus Domino server.
The largest impact on the processor occurred when all features were enabled. The processor time increased to
12.28%, which was a 2.28-time increase above the baseline value with no BlackBerry user accounts enabled.
Looking at the individual features, enabling the BlackBerry Synchronization Service along with the core email,
calendar, and sent item redirection had the largest impact to IBM Lotus Domino with respect to processor time.
For all other BlackBerry services, the processor time remained below 7%. The largest increase was noted with the
BlackBerry Synchronization Service enabled, which resulted in a 3.2-time increase from the baseline value. See
"Appendix: Calculations and data" on page 57 for more information. Results indicate that there is an impact on
processor use as more users are enabled and if the BlackBerry Synchronization Service is enabled.
The impact observed by RIM is specific to the workload applied and might vary site-to-site. The relative impact
observed occurs only on messaging traffic specific to what the BlackBerry Enterprise Server redirects. The impact
is not a multiplier that can be applied to existing processor use because the impact might also include load from
other applications, backups occurring on the IBM Lotus Domino server, or other IBM Lotus Domino traffic not
specific to BlackBerry redirection.
