Hi César,

on the most popular setup (Windows XP with IE or Firefox), Prototype and YUI
are really slow compared to the other frameworks (2x-3x as slow as JQuery).

On OSX Prototype actually seems to be a little faster than JQuery. It's
actually quite shocking how slow Javascript runs on Firefox/OSX compared to
Firefox/WinXP, especially if you take into consideration that My OSX machine
is an 8 Core Mac Pro and my XP machine is an emulated single core machine
running in Parallels desktop on the same machine.

Of course Sizzle will replace the current JQuery selector shortly, which
will make it much faster, even on OSX it seems.


Here are my results:

final times (less is better)

WIndows XP
                Peppy  Sizzle    EXT    Dojo   JQuery MooTools Prototype YUI
  IE 6.0        185    120       105    211     162     221      657     457
  Firefox 3.0.3  18     21        34     49      57      55       92      86


On Mac OSX
                Peppy  Sizzle    EXT    Dojo   JQuery MooTools Prototype YUI
  Firefox 3.0.3  38     37       135    126     192     176      177     401
  Safari 3.1.2   17     60        60     78      73      69       35     242
  Opera 9.52     39     31        79     98     119     140      173     346
