Are you caching the bitmaps produced by freetype? If not, that's
probably the best way to make it faster.

I have been investigating embedding freetype into one of our
platforms, and it looks great, but runs really slow. I was
wondering if there are any adjustments that I could make to the
engine to speed it up a bit? The rendering times on our platform
are unbearably slow. I would like a speed improvement of about
x32. (I know it is a lot to ask.)
I am thinking about changing the sub pixel resolution. Our
platform only displays in 16 bit color, so it seems to me that the
64x64 sub-pixel’s/pixel could be reduced. 64x64 would give 4096
units/pixel. I would think that this could be reduced to 32 units/
pixel for the 5 bit component, or 96 units/pixel for lcd
rendering. 32 units per pixel would need a 5x5, and 96 would need
a 10 x 10.
It seems like this could give me the speed improvements that I
need. Is this possible?
