Do you mean small files as render tiles?

This is already what we do on tile.openstreetmap.nl; I have modified 
renderd to render 'metatiles', but not to save them as metatiles. So on 
disk I have all seperate tiles. My webserver, based if the file exists, 
serves the file, or otherwise shoots in a render request like mod_tile 
would do.

So the main difference is that I never extract tiles, and never compress 
tiles. We still should plan some sort of benchmark to see if this method 
is better or worse then meta tiles. I think its better because the 
webserver is on less load, and the disk speed or filesystem should be 
tuned anyway.
