"Hm, looks like I should update my firefox…"
If you currently have an ff <3.5, dont upgrade it's very unstable. Did anyone else notice that? It has been crashing very often for me and a few of my internet-"friends".
My speed tests related with JS/AJAX image rendering give me this sequence:
FFox 3.5, Safary 4, Chrome, Opera 10, Explorer 8. FFox just fly.
It's strange but IE7 was many time faster toward IE8.
Opera is the most JS/Ajax unfriendly browser for me. Seems Opera team have own point of view about this :)
Firefox 3.5 working wonderfully for me; Chrome a close runner-up. Opera, however, is the slow one. One of the main reasons I don't use Opera is its javascript engine; my own experiences with Opera have tended to lag and/or result in errors with javascript-intensive websites.
Wow, really cool.
Shame about the obfuscation, is that a new irrfuscator thing you're playing with, or is a Mandelbrot set renderer top secret proprietary code?
