I don't think it is just btrfs. I am using XFS on top of software raid 1 in Maverick, and if I am doing any disk I/O (e.g. a big copy) dpkg will take a very long time to unpack. Stopping the disk I/O often won't solve the problem (maybe patience will).
I installed Brian Roger's dangerous sync free dpkg and I could install packages with heavy disk I/O without any significant lag or latency. dpkg Unpack would not wait for long periods with D - Uninterruptible sleep status. * XFS on RAID 1 * dpkg was slow to install during high I/O * dpkg w/o sync/fsync worked fine * During the first installation it was also very slow. -- maverick btrfs slow install https://bugs.launchpad.net/bugs/601299 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
