has anyone tried boosting this number, 256MB seems pretty low perhaps someone has tested with 512 or 768MB since someone mentions having tried with 1GB and it didn't work. Machine feels sluggish with this setting. Has anyone tested the 1 or 2GB Domain-0 limit, was it better than the zfs_arc fix? I am hoping to use my machine as a xVM/ZFS server. Is this being tracked by a bug report so we can get more information as to what is the root cause and when this is fixed so we can remove the work around from our systems. If an engineers help debugging this I'm handy with dtrace and the machine is not in use so I would be more than happy to investigate any ideas or fixes.
