Hi to all, I'm trying to investigate on a high memory usage, by an svg application I made. I've split the components into mini test cases, and I'm profiling each of them. What I find very strange is that a very simple svg application (described below) ranges from 30Mb to 186Mb, and what's worse, for a very long time (half the test time, 5h) the oscillations are very high. see the chart: http://img19.imageshack.us/my.php?image=pesosvg2he9.png
Is this the expected behaviour? the test case: It is basically the default SVGApplication from http://xmlgraphics.apache.org/batik/using/scripting/java.html it repeats forever -add a rect (first time only) -add an anim (translation of the rect) (first time only) -start the anim -wait for some time (1s) batik version is 1.7 the pc is running ubuntu 8.10, 64 bit, dual core, latest updates. netbeans ide & profiler http://img19.imageshack.us/my.php?image=pesosvg2he9.png package demo.test;
