Setting "zfs_arc_max" value in FreeBSD 8.

[Sherin George]

Hello,

I am trying to tune ZFS file system by setting "zfs_arc_max" value in
FreeBSD 8.

In solaris, it is achieved like this

=================================================
For example, if an application needs 5 GBytes of memory on a system with
36-GBytes of memory, you could set the arc maximum to 30 GBytes,
(0x780000000 or 32212254720 bytes). Set the zfs:zfs_arc_max parameter in the
/etc/system file:

set zfs:zfs_arc_max = 0x780000000

or

set zfs:zfs_arc_max = 32212254720
=================================================

But, I couldn't find /etc/system file in FreeBSD.

Could some one please guide me to correctly configure "zfs_arc_max" in
FreeBSD 8.
