[clug] very FAT linux filesystems or cluster pixes?

My first guess would be the block (and or fragment) size of the filesystem.

This determines the minimum allocation unit.  If all your files are smaller 
than the minimum allocation unit on file system 1 which has a say a minimum 
allocation of 2k and you copy them over to a filesystem with a minimum 
allocation size of 4k then you will naturally consume twice as much space.

It may even be a 4k (common on ext2fs and friends) verses an 8k min allocation 
unit - I am not particularly aware of such a filesystem, but would not be 
greatly surprised if some massive SAN style device did such a thing. Expecting 
to be full of bloated word documents rather than fast and light (I hope) web
