I am trying to batch / draw instanced sprites, so I don't have that many draw calls for each sprite.

This is where my engine creates a distinction between Static and Dynamic sprites.  Static sprites will be grouped together to reduce draw calls(meaning they just have to move together all the time...not that they can't move at all), while dynamic sprites will generally be kept as a single quad(or group of quads) which means it's own draw call.  If you're drawing all Dynamic sprites that can't possibly transform together, though, then the above suggestions are definitely the correct route.

That's a little generic. If you'd describe what you're trying to make, there might be other ( completely different ) techniques more important to optimizing performance. I can't imagine a game with primarily 4000 colored dynamic rectangles on screen at all time .. but maybe that's just me

No more help needed, I managed to get 120 FPS displaying 8100 'static' sprites (with color attributes, no rotation but with movement possible). When I've ran the same test but with dynamic sprites (color attributes for each one, rotation, movement, scale and all), I've got 100 FPS.
