Block device vs char device reads

I've been doing some benchmarking on reading from the 2 drivers. The
number of page reads the block device requires is many times more than
the char.  I'm poking through mtdblock.c trying to understand what it is
doing.  Is this behaviour to be expected?  Is there any way to optimize

I need to use the block device as I'm mounting JFFS2 on top but
performance has been terrible.  Any help would be much appreciated.
