HugePages: Why, what and how

This is meant to be a refresher because I’d expect that the Oracle DBAs out there know by now, at least, that HugePages exist and how to put them to work. But it may be the case that some juniors do not know yet and some seniors find this interesting as a return to the basics.

This presentation is about one of the very basic but not so well known performance related configuration tweaks. It is directed both to juniors that have just started dealing with production issues as a possible root cause of performance issues, but it will also be valid for senior who may never have encountered this kind of issue or just mean to refresh their knowledge and pin point a few details.
