Comments on: Rounding Error http://www.sporcic.org/2009/06/rounding-error/ Blog of Tim Sporcic Mon, 19 Jul 2010 08:33:13 +0000 http://wordpress.org/?v=2.9.2 hourly 1 By: Shea Frederick http://www.sporcic.org/2009/06/rounding-error/comment-page-1/#comment-181 Shea Frederick Fri, 19 Jun 2009 13:05:52 +0000 http://www.sporcic.org/?p=401#comment-181 I'm confused by your statement that "2.Ext, LLC, screwed the pooch in not using Sizzle for the selector engine" when it appears to be a rounding error that makes up most of the difference throughout the tests. So if jQuery executes a particular selection in 0.49ms and Ext Core does it in 0.51ms, then its Ext Core that is dubbed immensely slower? Tests like this take no real world scenarios into account, so im not a big fan of these kinds of things.
