Java2d

Im trying to use java2d but it seems too slow. I need to render 50 squares about 50pixels wide each. The thing is I need to do it really fast, like 5-10 times a second. anyone have any ideas?

In my experience it is the I/O extensive programs that only use 1-2 percent of the CPU that give me more problems in games than programs that would take 100% of the CPU and are CPU bound. 

It seems that two programs of the same priority that would each take 100% of the CPU if alone tend to take 50% a piece and just run half speed.

If two programs are I/O bound this does not seem to happen.  Neither runs smoothly even if only taking minuscule CPU.  I/O seems to be much less fine grain.
