Having the same problems: NFS (v4) share on freeBSD 8.03 up-to-date (Jan 2013) Ubuntu 12.10 64bit up-to-date (Jan 2013)
I can copy (read) big files with consistant rates at about 70MB/s from the NFS share. But when I write to the share it starts with 70MB/s for about 3 seconds, then transfer speed drops to 0 MB/s (really zero, see with nfsstat), and after 80 sec the transfer speed goes up to about 40MB/s for like 10sec, then it drops to 0 MB/s again, this repeats until the file is fully transferred. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/561210 Title: Writing big files to NFS target causes system lock up To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/561210/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
