More recent data (all my stuff, including jamvm, cacao, gcj, and classpath, are
compiled with -O0 though):

         #objects   Cacao   Jamvm   JDK 1.5   gcj
fillRect (9024)      430      650        30   230
drawRect (9024)      480      685        25   280
fillOval (2240)      675      830         4   580
drawOval (2240)     1160     1310         5   1200
drawLine (9024)     1660     1850        30   1700
drawArc  (2240)     1080     1300         3   1200

To be fair, I should recompile all my stuff with -O2 or -O3; I'm sure the
performance will be significantly better (though still nowhere near Sun)

With regards to antialiasing, I've found turning it off in classpath results in
minimal performance benefits (10-20%), while turning it on with the reference
implementation results in a huge performance hit (almost doubles benchmarks). 
Visually, classpath-without-antialiasing is comparable to Sun-with-antialiasing
though.
