------- Comment #6 from stern@rowland.harvard.edu  2008-12-23 05:59 -------
You can change the max_sectors setting through sysfs.  However the last time I
looked, the block layer limited max_sectors to 512 KB or something on that
order, so you can't get too much improvement.

Why is a limit of 120 KB unreasonably small?  All it means is that you have to
use more system calls to transfer the same amount of data.  Is anything wrong
with that?
