+====== Optimizations ======
+This page gives some hints and optimizations you can make to tune your MINIX 3 system
+to match your requirements.
+===== Increase the File System buffer cache =====
+<!> This particular hint is outdated. <!>
+If you have a large memory, you may also wish to increase the size of the file system buffer cache.
+To do this, change the value of the constant //NR_BUFS// in //servers/mfs/Makefile//. This value tells how big the cache is in disk blocks (normally 4 KB), so a value of, say, 4096, creates a 16-MB cache.
+Then rebuild and reboot the system.
