hi julie,
there is no real workaround. ("trop c'est trop.")
some possibilities although:
- switch of anti-aliasing
- try to render rectangles rather than circles. if they are that small
that won't make any difference. i did some tests a year ago with
randomly generated basic shapes. in order to render 5000 rects, ASV3/IE
takes ~4sec. the same 5000 with circles takes ~18sec. but you wont be
happy with your 36000 items anyway. 20000 rects -> ~12sec, 5000 rects
~25sec. (test were done on the same machine, an old PIII 750mhz, but the
on a newer machine, the differences stay.
- what's the monster image.gif in there. btw. GIF is not to be supported
by viewers according to the specification
- pregenerate your files and hardcode your circles. the generation
precess itself takes time to. if you really need this, build your svg
fragment with ALL cricles and append it once to the dom instead of
appending each circle.
a+
