[Bug 223238] Re: Extremely slow Ajax/Javascript/CSS performance in Firefox 3 using non-free nvidia-glx-new

 

See this thread at nvnews:
http://www.nvnews.net/vbulletin/showthread.php?t=152295 [launchpad.net bug views excruciatingly slow]

particularly this official reply from nvidia:
http://www.nvnews.net/vbulletin/showpost.php?p=2287025&postcount=7

.. in which AaronP states: "Thanks for reporting this. I took a look
today, and it appears that Firefox is using an enormous pixmap that
exceeds the GPU's maximum rendering dimensions, causing software
fallbacks. While we will attempt to make it as fast as possible,
performance would be greatly improved if Firefox would render using
surfaces that fit within the maximum renderable dimensions."

The bad launchpad.net performance in Firefox is bloody annoying, no
matter who is to blame. It does not help that launchpad.net itself is a
very slow website with high load-times per page view. Makes for a
sluggish impression in total..
