Confirming. Bruce, thanks for the information. The link you supplied earlier (attached again below) indicates that this issue is well known upstream (Linus T. no less). http://kerneltrap.org/node/14148
+++++++++++++ Note to Kernel Team: 1/ I can find no upsteam bug or enhancement request with regards to this matter. 2/ This does seem to be an issue of some importance & inconvenience with heavy io loads. 3/ Probably best summarised as "ext3 + fsync + heavy io = very poor disk performance". 4/ A workaround appears to be: adding mount options [noatime, nodiratime, data=writeback] 5/ Workaround for vim also indicated in above discussion. 6/ This is a fundamental design/functionality issue - maybe better handled as a Blueprint ( https://blueprints.launchpad.net/ubuntu ). Passing to Kernel Team to consider. ** Changed in: linux-source-2.6.22 (Ubuntu) Assignee: (unassigned) => Ubuntu Kernel Team (kernel-team) Status: Incomplete => Confirmed ** Changed in: linux-source-2.6.15 (Ubuntu) Status: Incomplete => Confirmed ** Also affects: linux-source-2.6.24 (Ubuntu) Importance: Undecided Status: New ** Changed in: linux (Ubuntu) Sourcepackagename: linux-source-2.6.24 => linux Status: New => Incomplete ** Changed in: linux (Ubuntu) Status: Incomplete => Confirmed ** Changed in: linux (Ubuntu) Assignee: (unassigned) => Ubuntu Kernel Team (kernel-team) -- poor disk performance during heavy io https://bugs.launchpad.net/bugs/43484 You received this bug notification because you are a member of Ubuntu Bugs, which is a direct subscriber. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
