For those that are interested, here is a new performance benchmark for Blackberry Enterprise Server 5.0

http://docs.blackberry.com/en/admin/deliverables/8864/BlackBerry_Enterprise_Server_for_Microsoft_Exchange-5.0-US.pdf

The interesting part is where you can see the impact of adding a BES server to your messaging environment. According to the document you're processor utilization will increase by 300% while your IO utilization will increase with 230%.

So not much performance improvement for Exchange 2007 in BES 5.0 but you get a lot of new features such as

IT Administrators

• Advanced Mobile Management through a New administrative console
• Built-in High Availability and Reliability
• Enhanced Application Deployment and Management
• BlackBerry® Enterprise Transporter Tool
• And more great features

End-Users

• Remote File Access
• Email Folder Management
• Enhanced Calendar Functionality
• Synchronization of public and private contacts
• Flag emails for follow up
• Listen to Windows Media Audio (WMA) files
• And more great features
