Ravi, I noticed in your previous post that you are hosting on localhost,
so I bet you're running windows. I think the size difference you noticed
is because even though the tile's size is only 200 bytes, windows FAT or
NTFS or whatever is set to store everything in 4096 byte minimum blocks.

First I noticed that most of my tile cache images were 200-1000 bytes
but they were taking 4096 bytes on the disk. Hence to reduce disk size I
increased tile size from 256x256 to 1024x1024. I thought this would also
reduce number of http requests and speed up the application.
After this change, the tile cache images generated were between 2k-10k.
However due to this change, ka-maps seems to come to a grinding halt.
Even for extent/zoom tiles that were present in the cache, it took very
very long time for ka-maps to finish loading the maps. Any idea why?
