you have a huge amount of memory. When turned on (to 1), this sysctl
allows the buffer cache to use the VM Page Cache to cache the
directories, making all the memory available for caching
directories. However,
the minimum in-core memory used to cache a directory is the

bytes. We recommend keeping this option on if you are running
any services which manipulate large numbers of files. Such
services can include web caches, large mail systems, and news
systems. Turning on this option will generally not reduce
systems. Keeping this option on will generally not reduce
performance even with the wasted memory but you should
experiment to find out.</para>
