Why are you trying to increase this size?
COSS is only efficient because it stores *small* objects and pre-loads a
bunch of closely related ones in each slice. Dumping larger ones into
each slice reduces the amount of pre-loading which is possible by
loading the slice. There is a threshold somewhat *less* than 1MB where
it becomes more efficient to use the OS disk buffering and stream each
file individually to the client wanting it. AUFS runs faster on large files.
