I think the true enlightenment in this article (for me, at least) is that Windows's tracing framework is far more powerful than I had realized. Being able to capture a system-level trace is an incredibly valuable tool. Until recently, I had thought that the only real tools out there to do this kind of analysis lived only on Solaris (DTrace). (As I recall, SystemTap gets part of the way, but does not reach far enough into userspace to really get a good view of what's going on -- is that still true?) It would be very interesting to augment Windows's performance tracing tools with some of the other things that DTrace has to offer -- pervasive low-overhead trace scripting seems like it would have made some of the other subsequent analyses that Bruce was working on much easier.
