When Windows 7 was released I had a performance issue that I was able to tediously work through with kernrate. It's my understanding that the tools have only improved since this time. I have a renewed interest in analyzing portions of my code paths with increased (perhaps unnecessary) delays. CPU utilization is uncharacteristically high, and I'd like to correct it.
What tools/workflow are people using to evaluate degraded performance in their drivers? I ran into this article about collecting detailed performance with xperf. Is this still the way to go? Are there alternatives I should consider? Anybody have a good walkthrough that could bring me up to speed quickly? I've found that most of the documentation details what the tool(s) can do, but rarely consider detailing usage scenarios.
