Technical Note: Impact of Supporting HTML and Rich-content Email Messages

Overview

BlackBerry

Enterprise Server version 4.1 SP6 supports users sending and receiving HTML and RTF

email messages using BlackBerry devices that are running BlackBerry

or later. By default, support for HTML and RTF email messages is turned on. You can turn off this

feature using the BlackBerry Manager.

This document outlines the expected impact of supporting HTML and RTF email messages on the

BlackBerry Enterprise Server. This feature might cause the BlackBerry Enterprise Server to use

increased amounts of CPU resources.

Load test conditions

Load tests were run to determine the impact of supporting HTML and RTF email messages on

BlackBerry Enterprise Server version 4.1 SP6. The load tests were conducted under certain load

conditions; the results experienced in your organization's environment might be different.

During the load tests, only HTML and RTF email messages were used. The messages were sent to

2000 BlackBerry device users.

The message load was applied to an environment that used BlackBerry Enterprise Server version 4.1

SP6 with support for HTML and RTF email messages turned on. The same message load was

applied to an environment with BlackBerry Enterprise Server version 4.1 SP6 with support for HTML

and RTF email messages turned off, and the results were compared. The load tests were run for 4

hours. Measurements were taken for the last 2 hours of the load tests.

The impact on the BlackBerry Enterprise Server varies depending on the workload characteristics of

your organization's environment and on the number of HTML and RTF email messages that users

are likely to send from and receive on their BlackBerry devices.

Production environments are expected to demonstrate a lower impact on the BlackBerry Enterprise

Server than the results discussed in this document, because the number of HTML and RTF email

messages are likely to be less than 100%, and the number of active BlackBerry devices that support

HTML and RTF email messages are likely to be less than 100%.

Results

When HTML and RTF email messages are sent and received, the BlackBerry Enterprise Server uses

up to 58% more CPU resources.

Conclusions

Monitor the CPU resources that the BlackBerry Enterprise Server uses. If the BlackBerry Enterprise

Server uses an unacceptable amount of CPU resources, you can use the BlackBerry Manager to turn
