Ian Huff has started a new blogging series on the new profiler features in Orcas.  The profiler is one of the most powerful tools (and perhaps the least understood) in the Team Edition for Developers product.  In his introduction, he writes:

Even if you are familiar with Visual Studio Team System you may not already know that a powerful profiler is included with both the Developer and Team Suite editions of that product. If you are not familiar with the profiler you can check out some of my earlier blog entries or TechNotes. In my new series of blogs posts, starting with my first post about the comparison documents, I’m coving all the cool new features added to the profiler that customers will finally be able to see in the upcoming Orcas Beta releases.

Do yourself a favor and read the start of what promises to be an interesting series of posts.
