<p class=MsoNormal><span style='color:#1F497D'>This made several suggestions

<p class=MsoNormal><span style='color:#1F497D'>I’ve been wondering if
putting the bayes in innodb format will help, although I’ve seen problems
with the innodb data file growing and really need to have innodb_file_per_table

optimised and the file size down.<o:p></o:p></span></p>
