Knowing John Resig, we'll get a blog post in 6 weeks showing a 30% speedup in jQuery in ie6 and 7. This man is a machine.
30% would be an unfair expectation to set for John :)

#13I think dynaTrace guys did something insane. Kudos!
Believe me I was doing some IE stuff (BHOs) and working with their COM extension model is one of my worst experiences (right after creating installer using WiX system).
btw. check out my web-dev tools at http://binaryage.com :-)

#14I wonder how this gets such detailed information about network and DOM events without injecting debug signals into the browser binaries?
It isn't as well known as it could have been, but IE can be controlled completely using OLE.

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.

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...
Re: Deep Tracing of Internet Explorer
#17How 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?
