Comment (by robscott):

 Hey guys, had a busy time last week, and this one got punted my side :) I
 am pulling together some nice big woocommerce dbs for this, but I think
 I'll struggle to benchmark anything meaningful, though I will try to get
 something concrete in next 1-2 days - i.e. works / doesn't work;
 improvement shown. Ideally, I'd like to test InnoDB vs MyISAM and various
 PHP versions, and also "Big WP" vs "small WP" in particular, to see what
 this throws up re improvements, though from what I can see, we're looking
 really for "any good reason we cannot push this live"?

 One of my issues is having been working around this for some time using a
 variety of fixes, I need to make sure I'm testing a virgin db which we
 have not been tuning :)
