As per name I am just an old git who is attempting to teach himself so apologies if this is the wrong place/query for here.
Anyway I have run mysqltuner and am working through the recommendations - some are easier and more obvious, some I've managed to solve with a little research but this one stumps me.
Can someone point me in the right direction for some literature/solution.
Thanks in advance
