Firefox 3.5 on Karmic is very slow to render SVG files

[Russell Wing]

Binary package hint: firefox-3.5

Expected:
I expect to be able to browse large SVG files as part of a web page at a reasonable speed
e.g. http://www.opensecurityarchitecture.org/cms/library/patternlandscape/251-pattern-cloud-computing
On 9.04 this page displayed at high speed on low spec hardware (AMD Sempron 3000)

Actual:
On a quad core AMD the rendering speed makes the web page unusable and hangs Firefox and Gnome intermittently.

Wondering if this is something to do with the recent change to NVidia drivers. Full screen replay in BBC iPlayer is now really jerky, even though normal view is fine. Strange....

[Russell Wing (wingfamily)]

Ignore NVidia reference and slow flash performance, now working. However SVG rendering is still incredibly slow... on a high spec machine, and way way slower than it used to be on much less powerful hardware.

The page you provide a link to above renders fairly quickly here, on an old AMD Athlon XP 2700+ with 1.5 GB RAM and an old ATI Radeon 9800 Pro 128 MB (R350). I'm running Ubuntu 10.04 "Lucid Lynx" alpha 3.

Perhaps it is an Nvidia driver issue after all.

[madbiologist (me-again)]

Is this still an issue for you on Ubuntu 10.04 "Lucid Lynx"?
