Analyzing SQL Server Performance: MDW

I recently discovered a tool that gives me a heads-up into performance across my SQL boxes:  MDW.  MDW provides graphical reports that allow me to quickly delve into the top waits in my system and what's causing them.  Rather than rehash what's already been said about getting MDW configured in your environment I'll hit some of the things that came up in my configuration that haven't been exhaustively covered in other areas of the web.  Check out my MDW link under the SQL heading to the right.
