I am experiencing the same behavior in a small network with 1 Gb ethernet connection between client and server. Large files can be moved over Samba quickly. The same files over NFSv4 move very slow and pause for long periods of time. I also see the high load due to nfsd threads.
This problem started with an upgrade to precise on both client and server. Before that, I had oneiric on the client and maverick on the server (and various other versions before that also worked well). -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1006446 Title: nfs4 causes enormous load in ubuntu-server making it unusable To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1006446/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
