Yes, perhaps I should have said "sheer number of allocations & deallocations". I was just surprised that it seems to grab and release memory much more often than anything else tracked by vmstat. > It does look like there is something else using a significant amount > of memory apart from arc, but arc might at least be the major one due > to its extremely greedy default allocation policy. I wasn't going to post again until somebody suggested trying this, but I think the name cache can be ruled out. I reduced vfs.zfs.dnlc.ncsize from ~13000 to 4096 with no appreciable drop in total memory usage. It seems to be stable with vm.kmem_size at 256MB, but the wired count has come dangerously close a few times. CraigReceived on Tue Apr 10 2007 - 00:04:56 UTC
