I've installed the -proposed kernel and ran 10 iterations of a block write soak test using stress-ng and measured the duration to perform 200000 I/O operations:
3.11.0-13-generic #20-Ubuntu : 127.6 seconds 3.11.0-14-generic #21-Ubuntu (-proposed): 78.5 seconds so the proposed kernel does radically improve block I/O write performance as expected. I have also thrashed ext4 with multiple kernel builds for a few hours and ext4 performs without any observable faults. I deem this verified and passed. ** Tags removed: verification-needed-saucy ** Tags added: verification-done-saucy -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1242812 Title: ext4 random block I/O write performance regression with 3.11 Saucy Kernel To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1242812/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
