The results of comment 23 suggest that the issue is not 100% reproducible. Can you please run the benchmark 3-4 times (presave/postrestore) and showall 4 results? One benchmark only, e.g. "simple read" will do.
Also please try putting a big file on disk (something like "dd if=/dev/zero of=bigfile count=64K bs=64K") and then doing "cat bigfile > /dev/null" after restoring. Please check if that makes performance more consistent. -- You received this bug notification because you are a member of Ubuntu Server Team, which is subscribed to qemu-kvm in Ubuntu. https://bugs.launchpad.net/bugs/1100843 Title: Live Migration Causes Performance Issues To manage notifications about this bug go to: https://bugs.launchpad.net/qemu/+bug/1100843/+subscriptions -- Ubuntu-server-bugs mailing list Ubuntu-server-bugs@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-server-bugs
