Scott fine, RobG idem, I'll talk with @phiggins as soon as I'll have
To me could make sense to write a PureCheat library to put beside
PureDOM, not a replacement, since in any case, innerHTML could be a
As example, the first test via innerHTML will potentially destroy
every attached event handler to existent content.
I have that fast version, I hope to have time to create a full
PureCheat version as well.
P.S. same webreflection that blogs sometimes in Ajaxian, that is kinda
still me ;-)

"Pure DOM" was written by a human being, just like the rest.
Obviously they made some mistakes as it is nowhere near optimal
(particularly in Webkit-based browsers).
And realize that the tests for each framework are different. I
purposely optimized for conciseness, not speed. Most of the others
are using built-in DOM methods for at least some of the test
functions. My point is that I have the best of both worlds. If you
want pure speed, use the more verbose API. If you like jQuery-like
gibberish, chain the object methods together like I did in the test
functions. It's flexible that way. ;)

Which My Library? The one with QSA or not? It makes a small
difference in TaskSpeed (and a huge one in SlickSpeed).

None of the others comes close to supporting IE6 properly (e.g. they
just call getAttribute without regard to the broken implementation).
Of course, that's more of a concern for SlickSpeed.

That's with _every_ module included (e.g. Flash, audio, scrolling
effects, etc). Most of them are not needed by these tests.

That's what the builder is for. ;)

I looked at some of them and more than one was using native DOM
methods, so it seems they are apples and oranges. I remember that
YUI's weren't particularly concise.

Sure. It's just enough to run these tests. ;)

My point is that it supports the "concise" coding style that is so
popular among major library enthusiasts (and is very fast doing it).
It also supports more traditional methods (even faster).
And I have found after extensive testing that the margin of victory is
wider on older machines, older browsers, phones and Webkit-based
browsers. Faster PC's running IE and FF have closer results.
And ultimately, if a library that is supposed to make cross-browser
scripting easier fails to handle attributes properly in IE or resorts
to non-solutions like browser sniffing, it should be disallowed (which
rules out all of the others). I plan to demonstrate that on the test
pages in the near future. It should come as no great revelation to
regular readers of this group though. ;)

I'd say your contributions have been pointless so far. Yes, you
should make the "baseline" as fast as possible without sacrificing

They are on older PC's (and mobile devices). 60% faster in Chrome/
Safari on an older (but not ancient) XP box. Lots of "normal people"
have such equipment, of course.
