"Instead of piling on more, often increasingly complex, tools, I believe what is needed is a clear roadmap and methodology for systematically addressing SQL Server Performance issues."
This is the most on-the-mark statement I have heard come from a SQL guru in a long long time. God bless you Tony for saying it. However, witnessing that Microsoft seems to love complexity over simplicity and often introduces tools and features that are never fully explained, I fear we are doomed to just more of the same. If there was any way to get the SQL community to settle on a good 'standard' (if possible) methodology and drive Microsoft and the user community that way, I'd be all for it.
There's no such thing as dumb questions, only poorly thought-out answers...
