That's a pretty good and deep look at MS internals. I've been trying to figure out what facebook's flow is so darn bad on Windows. Using this approach might actually give some results.

Is this the Facebook web page? If so then using Chrome's profiling tools would be the best choice. Although, I find most web pages so complicated that they are hard to understand well enough to optimize.

For any native app performance problem I highly recommend xperf/ETW. It's an amazing tool that almost always lets me figure out the problem. tinyurl.com/etwcentral.

No, I meant the flow binary: https://github.com/facebook/flow

It's a static typechecker for JS, somewhat similar to typescript. It's written in OCaml, which one of my colleague tells me has some perf issues in Windows.
