Mmap doesn't use that value so it's fine to increase it higher. There is no need for multiple segments as it has only a size limit for SHM and yes it gives some overhead. > Does that mean that multiple segments aren't working at the moment > or do I have some configuration error? multiple segments make only sense for SHM... not for mmap. However you could say that for mmap the allocated memory should just be apc.shm_segments * apc.shm_size as that's what I would expect atleast. regards, Derick -- Derick Rethans http://derickrethans.nl | http://ez.no | http://xdebug.org
