I hate when people post questions, find their own solution, and then never answer their own question for the sake of future poor souls, so I'm following up on what I've found.
A major issue with our performance was related to the use of the "visibility" attribute (specifically "hidden") compared to using the "display" attribute (set to "none"). For a given location in our displays, this location may show any one of a number of different images that represent the current state of something, let's say, the current state of the moon (waxing, waning, quarter, half, full, etc). As the SVG files are currently setup, the images that are not visible (not reflecting the current state) are "hidden" via visibility="hidden". When I modified the SVG to use display="none" the displays were able to be called up **4 time faster**. Checking the SVG spec (http://www.w3.org/TR/SVG11/painting.html#VisibilityControl) indicates why. From the spec: "When the 'display' property is set to none, then the given element does not become part of the rendering tree." So, you can see that Batik can handle the GVT build and render much more easily because it can "ignore" the items that are set to display="none". In the old way, visibility="hidden" still results in the non-current images being rendered. Thanks to everyone for your help. I'm sure that you all would have pointed this out immediately if I would have been able to post a file, but I did not have the liberty to do so. ----- To unsubscribe send a message to: [EMAIL PROTECTED] -or- visit http://groups.yahoo.com/group/svg-developers and click "edit my membership" ---- Yahoo!
