BlackBerry Enterprise Server for IBM Lotus Domino Performance Benchmarking

BlackBerry MDS Connection Service traffic

When implementing the BlackBerry MDS Connection Service, consider both the rate at which data is sent to
BlackBerry devices and the amount of transcoding that the data requires. Do not push too much data that requires
transcoding to BlackBerry devices when messaging traffic is heavy; doing so might cause message delivery to
slow. If you often push data that requires transcoding, the system might experience processor bottlenecks. There is
less control over the rate at which pages are pulled, so you should control the rate at which content is pushed. If
you plan to push a large amount of data that requires transcoding, consider installing the BlackBerry MDS
Connection Service on a computer that is remote from the BlackBerry Enterprise Server computer.

BlackBerry Attachment Service traffic

Potential issues processing attachments might occur in the following situations:
• when processing concurrent requests
• when processing large attachments
• when processing complex attachments (for example, .pdf files or ASCII text)

Wireless message reconciliation

When there are pending changes on a BlackBerry device that require immediate reconciliation, users can reconcile
messages from the BlackBerry device manually using the Reconcile Now option in the BlackBerry Desktop
Software. If users use the option excessively, a significant increase in network traffic might occur.

BlackBerry Configuration Database

The BlackBerry Enterprise Server Version 4.1 requires either Microsoft Desktop Engine (MSDE) 2000, Microsoft
SQL Server 2005 Express Edition, or Microsoft SQL Server 2000.
There are two limitations that prevent MSDE 2000 from scaling:
• The workload governor is activated if more than eight concurrent requests are made.
• The maximum size of a database cannot exceed 2 GB. If users have 16-MB BlackBerry devices, database
memory should not exceed 1 MB for each user account. However, if users have 32-MB BlackBerry devices, the
database memory use is greater.
If you are enabling more than 500 BlackBerry user accounts, you should use Microsoft SQL Server 2000. If you
enable a large number of user accounts with MSDE 2000, monitor the Event Viewer for warnings that indicate that
the workload governor has been activated. There might also be an event from the BlackBerry Enterprise Server
warning that MSDE is approaching its 2-GB database size limit. These warnings indicate that you should upgrade
from MSDE 2000 to Microsoft SQL Server 2000.
RIM conducted the benchmarking of the BlackBerry Configuration Database using Microsoft SQL Server 2000.
RIM has not evaluated the limitations of Microsoft SQL Server 2005 Express Edition at this time. Microsoft SQL
Server 2000 is the updated equivalent to MSDE 2000.
