After a load tests, I've found the same anomaly with btrfs. I'm using a 80GB btrfs raw device, 16GB memory, 16 CPU threads:
BTRFS: Time 24.026 32 54.584 64 125.520 128 272.835 256 809.038 512 3451.172 1024 So the pinch point happens later than with ZFS, but there seems to be a scaling issue here too. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1567557 Title: Performance degradation of "zfs clone" when under load To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/zfs-linux/+bug/1567557/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
