I use them all the time. The have fairly large CPU benefits in Virtualized environments, smaller but still noticeable CPU improvements in physical environments. The key item is to allocate enough hugepages for your entire sga. If you are using OVM, make sure your version supports them directly, early versions translated them to standard page size.
