In the Composition Editor, you can easily: set your own Network Emulation Profiles, select built-in profiles, or create new profiles.

Network Emulation can be enabled at the Distribution level. To open a profile dialog, click Browse.

Once you have set a profile, you can enable Shared Bandwidth with Server.

• If the Shared Bandwidth per Server option is checked, all virtual users in the same distribution will share bandwidth. This option will emulate some real world scenarios; for instance, if all users in a small office shared bandwidth to connect to the Internet.
• If the Shared Bandwidth per Server is unchecked, bandwidth will be allocated to each virtual user.
