​General comment:​
​this type of questions sounds very much like the
"studies on the internet say.." line from Dilbert strips.


You are taking a random sentence from
a random document, the conclusions drawn by the author
(assuming they are correct, i have no idea) may
depend so much on testing conditions that it is pointless
to reason how they apply to your case.

Please run _your_ experiment in the configuration that you
care about, then if you have any issues report them
and your configuration. That is something we can discuss about.
