In NL we have implemented a High Performance on demand rendering and
caching server and were experimenting with different tile sizes (and
specially layer sizes!) Currently we do a color reduction (requires less
bits), in this way the tiles get smaller so the active area the tile
represents can be increased. I agree with your optimisation 'just under
blocksize'. But dense tiles increase in size rapidly.
If you want to take a peak: http://tile.openstreet.nl/
I think deduplication could be another interesting method to reduce the
amount of tiles.
