The mods to the RM driver to allow dynamic modification of the timing
parameters work, and the effect is quite striking.  The default settings
of the search/commit times are 2/6.  With a setting of 5/10, a simple
benchmark (reading a huge file a block at a time) runs twice as fast!
I've left things set at 5/10, and added an srm command to /etc/rc to
keep them that way.  This may not actually be optimum, but it's a lot
better than 2/6.  More tuning to follow.
