CGContextFillRect - is there a faster way?

Hi,

I'm pretty new to Mac programming, so forgive my beginner question:  I have a carbon component (an audio unit) which has a dynamically updating display, and I'm finding that the graphical performance is a bit of a problem for me - its just too slow.

My code seems to spend much of its time trying to fill in a rectangle with a solid colour by calling CGContextFillRect.  Is there a quicker way of doing this sort of thing?  How much does it depend on what kind of CGContext I'm using? (I'm using a CGBitmapContext)

Thanks for any help.

Paul
