Network Use - Blackberry ENTERPRISE SERVER FOR IBM LOTUS DOMINO - - PERFORMANCE BENCHMARKING GUIDE Manual

BlackBerry Enterprise Server for IBM Lotus Domino Performance Benchmarking

Network use

RIM collected the network bytes /sec counter on the IBM Lotus Domino servers to understand the impact of
enabling BlackBerry user accounts with specific features on the network infrastructure from an IBM Lotus Domino
server perspective.
Out of all the data collected, RIM observed that the largest increase in network use occurred when all of the
features that were benchmarked were enabled. RIM observed that the BlackBerry Synchronization Service, along
with the core BlackBerry features enabled (email, calendar, sent item redirection) caused the largest increase in
network use. The network bytes /sec grew from 6.85 Mbps to 10.96 Mbps, which was a 60% increase from the
baseline value without BlackBerry user accounts enabled. To make sure that enough bandwidth is available
between the IBM Lotus Domino server and the BlackBerry Enterprise Server, your network administrator must
consider this increase.

The impact observed by RIM is specific to the workload applied and might vary from 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 disk traffic because the impact might also include activity
from other applications, backups occurring on the IBM Lotus Domino server, or other IBM Lotus Domino traffic not
specific to BlackBerry redirection.
