You do use UFS, right ?
Yes.
I've run test on ZFS.
Mem: 2645M Active, 363M Inact, 2042M Wired, 1406M Buf, 42G Free
$ ./mmap /mnt/random
Mem: 3669M Active, 363M Inact, 3067M Wired, 1406M Buf, 40G Free
It eats 2Gb as I understand.
# umount /mnt
# zfs mount -a
Mem: 2645M Active, 363M Inact, 2042M Wired, 1406M Buf, 42G Free
$ cat /mnt/random > /dev/null
Mem: 2645M Active, 363M Inact, 3067M Wired, 1406M Buf, 41G Free
That's correct - 1Gb.
About "Buf" memory. Is this reasonable to set it to 10% of physical
memory? I've lost 10Gb by default on machines with 96Gb.
