Great, thanks! I've got some terms to google. For those who follow in
my footsteps, on Ubuntu the package 'sysstat' needs to be installed to
use iostat. Here are my reference stats before starting to experiment,
both for my own use later to compare and also if anybody sees anything
amiss here then I would love to know about it. If there is any fine
manual that is particularly urgent that I should read, please do
mention it. Thanks!
