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. -- Best Regards, Sherin
