The disk buffer system should cache the really crucial inode blocks for you. It's been a while since I've been inside a BSD I/O system, though, so you probably want to double check this on -hackers. If you really feel that's not good enough, I once added a cron job that every so often just read in the directory structure for the crucial directories. This caused them to be refreshed in the cache, and thus kept in memory. For added performance on multi-user freebsd boxes, I was wondering if > there's any way to load the inode structure in memory.
