If you're into pondering some more tweaks:

-i InodeSize   is tunable

system pool : --metadata-block-size is tunable separately from  -B 
blocksize

On ESS you might want to use different block size and error correcting 
codes for (v)disks that hold system pool.
Generally I think you'd want to set up system pool for best performance 
for relatively short reads and updates.
