True the L2ARC requires some ARC consumption to support it, but for typical user data, it's a huge multiplier... The ARC consumption is static per entry (say, 176 bytes, depending on your platform) but a typical payload for user data would be whatever your average blocksize is ... 40K, 127K, or something similar probably. _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
