Microsoft released a new "Exchange Processor Query tool" to enable you to quickly locate the SPECInt 2006 Rate value for your server. This tool automates the manual steps, described in Mailbox Server Processor Capacity Planning TechNet article, to determine your planned processor's SPECInt 2006 Rate Value.
"To run this tool you must be connected to Internet. The tool will take your planned processor model as input and execute a web query against the spec.org website returning all test result data for that particular processor model. The tool will also calculate an average SPECint 2006 Rate Value based on number of processors planned to be used in each mailbox server. Once you complete the steps you can plug result value for your planned processor into megacycles per core field in step 5 of the input range in Mailbox Role Calculator to assist in Exchange 2010 server planning. If your particular server model isn't listed in the dataset returned by the web query you can use the calculated average value and input that number into the megacycles per core field," explained Microsoft.
