Are anyone at Sun's Java2D team aware of this problem?
If I turn on 'translaccel' graphics primitive rendering slows down by about 30%, if it is anti-aliased.
It is a regression since it's in 1.5 (final) but not 1.4.2_05.
If it's a known problem, I won't nag about it, but if it's not I can make you a test case and investigate a little further. Maybe even have a battle with the bug parade..

ps. Filed this on java.sun.com/products/java-media/2d/mail/java2d-comments.html a couple of weeks ago, but there was no answer.
