Hi I'm using FreeBSD and nginx as a web server serving static files. I always like the "buffer cache" which lets frequently used files stay in memory rather than read from disk again. I have a new server with 32GB of ram and I notice a lot of memory is listed as "Inact": Mem: 688M Active, 26G Inact, 3758M Wired, 823M Cache, 3281M Buf, 173M Free What's preventing this ram from being used as buffer cache for files on the hard disks? Is there a limit or a tunable stopping it? I never had a server with this amount of ram before. It's a very busy server, I'm sure a lot of files are accessed regularly as the disks are always busy. Using 9.1 amd64: FreeBSD richard 9.1-RELEASE FreeBSD 9.1-RELEASE #0 r243825: Tue Dec 4 09:23:10 UTC 2012 root@farrell.cse.buffalo.edu:/usr/obj/usr/src/sys/GENERIC amd64 Many thanks
