Exchange Load Generator (64 bit)

Brief Description

Exchange Load Generator is a simulation tool to measure the impact of MAPI, OWA, IMAP, POP and SMTP clients on Exchange servers.

Overview

Use Microsoft Exchange Load Generator (LoadGen) as a simulation tool to measure the impact of MAPI, OWA, IMAP, POP and SMTP clients on Exchange servers. LoadGen allows you to test how a server running Exchange responds to e-mail loads. To simulate the delivery of these messaging requests, you run LoadGen tests on client computers. These tests send multiple messaging requests to the Exchange server, thereby causing a mail load. LoadGen is a useful tool for administrators who are sizing servers and validating a deployment plan. Specifically, LoadGen helps you determine if each of your servers can handle the load to which they are intended to carry. Another use for LoadGen is to help validate the overall solution.

Important! LoadGen should be used only in laboratories that have no connection to the production environment. This tool should not be used in any way in a production environment or an environment that is mission critical or contains important information of any kind anywhere in the network.

Note: The XML configuration file schema in this release has changed from previous versions. You will need to create a new XML configuration file with the Load Generator UI. The existing topology will be marked as un-editable if there are users created by previous versions of Microsoft Exchange Load Generator. Add your remote client machines again, and then save the updated configuration XML.

Note: If you use the recipient management features of this release to create users or other recipient objects and you have one or more Exchange Server 2007 servers in your test topology, you must run the Load Generator application with user credentials that have permission to manage Exchange recipients. The directory access account specified in the application configuration will not be used for this purpose.

Note: This version includes scripted module functionality which enables load generation for OWA, IMAP, POP, SMTP.

Note: There have been reports of errors when trying to install Loadgen. The errors will show in the event viewer message as "Action START_REMOTE_SERVICE". The KB article below will help you resolve this issue.
