Hi all,  

  After the thread about hugepages a while ago I became interested in them, and told the SA about them. He said it's viable in most of our environments, so it now lies with me to decide where to use hugepages. As I have no experience with this, I'd very much appreciate any pointers as to how to decide whether to use hugepages or not in a given environment. Also, if you know of a way to 'benchmark' de performance to have something to show the customer (as the change would require some downtime). I think it goes without saying that this will be tested in (redundantly enough) testing and QA environments way before we even consider trying it in pre-productive and productive environmets.  

Thanks in advanced
