User Agent: Mozilla/5.0 (Windows NT 6.1; WOW64; rv:20.0) Gecko/20121130 Firefox/20.0 Build ID: 20121130030747 Steps to reproduce: Open http://jsfiddle.net/X5sNP/2/ . Actual results: Firefox 20 (Nightly) is very slow at rendering this on an ATI Radeon HD 7690M XT and on an Intel integrated desktop graphics board. IE 10 is a bit faster, while Chrome is much faster.
Dup of bug 817446 -- changing the Array instances to appropriate typed arrays causes perf to be dramatically faster. Bug 817446 tracks the cause of the slowness of regular arrays.
