Loadgen latest..

An updated version of the Exchange Load Generator: 'Loadgen' has now been released.  If you are going to be using Loadgen make sure you grab the latest version from here: Tools for Exchange Server 2007 or download from here: Exchange Load Generator (64 bit) or here: Exchange Load Generator (32 bit) ...

This update includes a number of improvements to the initialisation process, there is better scalability and I'm told it is much more intuitive to use.

"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."
