I wonder how this gets such detailed information about network and DOM events without injecting debug signals into the browser binaries?

Can't you do this through COM? (Isn't that the point? I dunno, I've never programmed windows stuff...)

Yes. You can do nearly all this stuff just by hooking into MS's published interfaces. I've done many pieces of it myself, but seeing it tied together like this so comprehensively is amazing.

30% would be an unfair expectation to set for John :)

under or overestimate?

Under. John is known for his insane optimizations, achieving speed ups of up to 800%. http://blog.jquery.com/2007/07/01/jquery-113-800-faster-stil...

How hard would it be for browser makers to make the kinds of information this tool needs readily available (instead of the tool maker to write very low-level code, basically a giant hack) and how much work would this save for the makers of tools such as dynaTrace?
