Define "release" (or rather "really release"). It can get marked as free in a Perl sense, but not (necessarily) be returned to the OS. So from the OS point of view it is still used by the perl process that (once) allocated it. This all depends on how your perl is compiled too, like with what memory manager. > By the way, I found the hash table use much more memory than the > array.
