Hi MJ,
It is a bit difficult to give suggestions in such a
general situation. As others have mentioned a 500K
SVG is a fairly large file (you can't compare bitmap
file sizes with vector graphic file sizes).
What are the predominant elements in the SVG file?
Text? image? path? other basic shapes? use?
There are also Batik specific mail lists which as
you dive down a bit deeper in the code might be a
useful reference.
http://xml.apache.org/batik/mailList.html
But right now you are just talking about SVG in
general so this is the place to be.
