In case you missed it in my last post, SQL Nexus, the SQL Server performance analysis platform built by Bart and me, has been released via CodePlex. Here's a post post where I talked about how Nexus works. And here's the link to its page on the CodePlex site.
While I'm at it, another tool you might find useful is SQLDiag. It ships as part of SQL Server 2005 and later. Read about it here and here.
For a high-speed, lean, command-line analysis tool for Profiler traces, check out the Retrace tool we released into the wild yesterday here.
