Why is IE8 rendering a page with JavaScript unusable while FF is doing fine?
LINK TO THE PAGE NO LONGER ACTIVE, THANKS FOR VISITING, Rene
Hi,
I have a page here and I can't understand why is IE8 rendering this page so slowly. Or开发者_如何学运维iginally I thought it was the scrolling text at the top but it's not as I commented it out with no progress. So then I profiled with developer tools for IE8 and it shows a lot of anonymous functions running which I suspect come from jquery (which is not loaded by me directly) but the developer tools cannot show me the source code for those functions. So I can't pin down the problem on what are those phantom functions running from or why as I have no experience with jquery. I noticed that those functions do not run in FF when I profiled it with FireBug so maybe something is running for IE but not for FF ? I am a bit lost.
Any help/suggestions is greatly appreciated!
Thanks so much, Rene
I was able to see the process jumping between 79MB and 65MB off and on. It may be an issue of memory not being freed up or perhaps an inefficient background operation that is hanging everything up.
I would go with meder5's advice. I would comment any and all unnecessary code and start with the bare minimum and track performance till you find the bottleneck as you add pieces back in.
Hi I also tested in Chrome 8. Frankly, the page is neither fast in IE nor FF nor Chrome. But its relatively faster in FF and Chrome much than IE. I suppose it has something to do with the different mechanisms of FF/Chrome and IE use handling contents.
By the way, I appreciate that you guys can do very nice animation with javascript&jquery,
