Use Microsoft Exchange Server Stress and Performance (ESP), a highly scalable stress and performance tool for Exchange, to simulate large numbers of client sessions by concurrently accessing one or more protocol servers. ESP includes multiple modules that you can use to simulate a wide variety of protocols and loads. You can run modules concurrently from multiple hosts, thereby more realistically simulating physically separate client machines. There is no limit to the number of computers on your network that can host ESP modules. This version is the first release on CNET Download.com.
