Web Page Performance in a Standards Compliant and Interoperable way

Speaking of standards -- why does IE9 have a NEW property on the window object that returns NULL?

window.ActiveXObject

msdn.microsoft.com/.../ff974676%28v=VS.85%29.aspx

This is the kind of crap that got Microsoft in trouble in the first place... even more awesome is the notes that say if we as developers put stuff there in the past, to stop it...

Arghhh!!!!!

The iframe element should follow the css border:none and overflow:hidden to hide the border and scrollbar.

frameborder and scrolling are no longer allowed in the HTML 5 spec.

@ Uhm

It also lacks a spell checker, which is your case would be a non starter.

This looks great guys! Glad we don't have to use crazy hacks to get these metrics!

A couple of questions/enhancements:

- support SSLStart and End to figure out SSL Handshake time. Currently I am assuming it goes into the Connect.

- what would be the wait time? So once connection established (ConnectEnd) the request is Sent, and than the client waits for the server. Is it :responseStart - requestStart - the concern here is there is no RequestEnd (usually request is super fast, 1 packet, but there are some cases where it is slow say an ASP.net page with a vert large ViewState?)

Sounds cool, something we need in our completly Ajax based webapplications is a good way to find Memory leaks,

is finding stuff like that something that will be added in IE9?

For example I would really want to know if a HTML DOM Element couldn't be cleaned up by the garbage collector

because there is still an eventhandler attached to it.

This is quite cool indeed! It certainly shows that IE9 is now a capable modern web browser unlike all previous versions of IE. Congratulations on such speedy, trackable results!

One thing though. Are these times subject to delays due to IE Addons? e.g. If I have the "WhackySlow Bar BHO" installed am I going to see these numbers grow wildly without any explanation or ability to debug?
