 Well, that was a surprise - the SSD is indeed faster (tested
building a kernel), but by less than 2% on this machine.  So in
practice no noticeable difference.  And the differences between the
various i/o schedulers on the SSD are lost in the noise.

 Using hdparm, buffered reads were all-but identical between the
spinning disk and the SSD so I really doubt there is any way to
significantly speed up this box.

Nanny Ogg usually went to bed early. After all, she was an old lady.
Sometimes she went to bed as early as 6 a.m.
