I think it is access to the physical hard drive, not particularly NFS that is your bottleneck and it is related to normal buffered writes. You'll see about the same pattern if you dd between two local hard drives. If your nfs mount has the sync option it might make things worse. -- Les Mikesell lesmikesell@xxxxxxxxx
