BTW about other operating systems: It looks like FreeBSD is already clever enough to use super pages as it calls them. This is something like Linux's 'transparent huge pages' except apparently somewhat more transparent. Though I wonder if there is some advantage in adding a MAP_ALIGNED_SUPER flag to the mmap request. It looks like MacOSX can do it with VM_FLAGS_SUPERPAGE_SIZE_ANY but such mappings are not inherited by child processes.  https://lists.freebsd.org/pipermail/freebsd-hackers/2012-June/039018.html  https://www.youtube.com/watch?v=0wIxny-n_Mg <-- a really good talk about this stuff! -- Thomas Munro http://www.enterprisedb.com -- Sent via pgsql-hackers mailing list (email@example.com) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
