The venue is the next Seattle Code Camp meeting on September 13 at Seattle University. See https://seattle.codecamp.us/Schedule for details.
The presentation slides are available on SlideShare here.
I am also scheduled to give a similar presentation at the October meeting of the local .NET Developer’s Association, to be held an the main Microsoft Redmond campus after hours on October 6. See http://www.meetup.com/NET-Developers-Association/ for details.
I have written a little something about this topic in the past, for example, here: http://performancebydesign.blogspot.com/2013/10/page-load-time-and-yslow-scalability.html. The latest presentation expands upon the ideas presented there, but also introduces a new ETW-based tool for monitoring web application response times for Windows apps, which I will be demo-ing.
Of course, I will have a lot more to say on this topic in future blog posts on the subject..
