Faster Dots than drawCircle()?

Ive got a LOT of small projectiles (bullets) flying around my game. They’re really small, in fact they only need to be one pixel each.

Right now I’m using drawCircle with radius 1.

I’m looking to speed up the game in any way possible, and Im thinking that drawing a circle is pretty complicated math-wise when all I want to do is draw a single pixel. I switched to drawRect() instead but I havnt noticed any increase in speed. Is there something even simpler I could be using? drawDot() or drawPixel() would be perfect but of course those arnt part of the Graphics class.

Thanks!
