Paint makes "Uber-Lagg"

Hey, like the title says ...my paint makes my script lagg pretty much...
It has much to calculate but it has to be informative...
Can any1 tell me how to make it not lagg so much...?

P.S:Sry for bad english:S I'm a german kid:D

What's in your onrepaint method?

You probably have an infinite loop inside it or you have to much anti-aliasing. This usually happens when using Inventory methods inside the paint void.

I think I solved it on the IRC.
He had something like:
final Image img = getImage("some url");
in his repaint XD

Lol, uber lag
