optimizing the performance of svgrasterizer

[Matthias Grumet <ma...@grumet.at>]

hello,

we are using batik's svgrasterizer for a game, but are experiencing
performance issues, when rasterizing SVGs.

we believe that the function
org.apache.batik.gvt.renderer.StaticRenderer.repaint(Shape)
creates quite a lot of temporary objects which triggers garbage
collection a lot which results in occasional stuttering of the game.

so i was wondering, if there are any options or configurations to
batik in order to have the svgrasterizer perform better in terms of
garbage collection and CPU time.

we want it to create as little garbage as possible and as little CPU
time as possible.

thank you,
matthias

I don't know if there's any built-in switch to optimize here, but have
you experimented with the JVM settings? Like "-server" and/or
"-XX:+UseParallelGC". Just a thought.
