Low FPS with a lot of sprite display

Hello,

I'm student and i try to do a game in 2D for my project in first year. I'm too beginner in C ++.
I'm trying to do this game with openframework and i have FPS problem for the map display.

   // 32 pixel * 32 pixel = image size.
nbrCaseX = ofGetScreenWidth() / 32;
nbrCaseY = ofGetScreenHeight() / 32;

for (int x = 0; x < nbrCaseX; x++) {
	for (int y = 0; y < nbrCaseY; y++) {
	sprite.drawSubsection(x*32, y*32, 32, 32, 608, 0, 32, 32);
	}
}

But with this draw, FPS is now 10-15 fps maximum.

How can I optimize the code for a lot of sprite display ?

Thanks
