Perhaps you should read the QFS documentation and/or source. :-)
I probably should...
QFS, like
other write-forward and/or delayed-allocation file systems, does
not incur a
seek per I/O. For sequential writes in a typical data capture
application,
there are no seeks at all (save for those required to move
sequentially).
Then the gains from giant I/O size should not be that large (do we
have number here ? are we talking small % points)
unless the I/O scheduler is less efficient than ZFS'
