I apologize. Again you are correct. However, I don't see that helping. The VM doesn't associate arc cache pages with ZFS vnodes. So I don't see that helping in this case. We need some way of coupling the two. The challenge with the ARC is that it caches logical disk blocks, not file pages. Cheers, Kip
