[webkit-dev] SVG performance benchmark
Wed Apr 18 23:44:37 PDT 2007
Webkit makes a very poor implementation for those who cannot, don't
wish to, or do not have access to a mouse.
Keyboard navigation isn't supported, so the time to load is really
irrelevant if the user has any input.
Opera doesn't support foreignObject, though there is a temporary hack.
Client side support for more than one language isn't available.
Camino or firefox are easy winners for getting the most out of http://
Client-side scripting isn't used at all, SVG, CSS and HTML.
manipulating the DOM via script may offer the author exciting
opportunities, however there are many good reasons not to use client-
side scripting. One being that it interferes with assistive
technologies, and is frequently turned off.

Working a lot with SVG on the Mac I can confirm that the Webkit
implementation is among the faster. In some cases the Adobe SVG
viewer is still faster, but Webkit is faster when it comes to DOM
manipulations, creating/changing/deleting a lot of elements. I still
have to track down the cases where the Adobe viewer performs
significantly better than Webkit.
Opera 9 is probably the most complete browser when it comes to SVG
features, but it is slower especially when the size of the SVG DOM is
larger than >5-10000 elements. Firefox SVG on the Mac is awfully
slow, maybe due to the fact that Cairo is poorly implemented on the
Mac? (just a guess). On Windows, Firefox SVG performs a lot better,
on Linux I get very different results, depending on XServer/Graphics
It will be interesting to see how well webkit performs for animations
and filters, once they get implemented in future releases.
