Tests on a memory backed pool show performance improvements of ~15-22% for AES-CCM writes, ~17-20% AES-CCM reads, 34-36% AES-GCM writes and ~79-80% AES-GCM reads on a Sandybridge x86-64 CPU, so this looks like a promising optimization that will benefit a lot of users. == The fix == Backport of upstream 31b160f0a6c673c8f926233af2ed6d5354808393 - this is already backported in Groovy ZFS 0.8.3-1ubuntu13 == Test case == Run ZFS performance tests from ubuntu_performance_zfs_encryption ubuntu kernel team autotests. With the fix the encryption runs significantly faster, as noted earlier in the SRU justification. + Also test with the 4 types of ZFS ubuntu autotests, should not fail any + of these. + == Regression Potential == This fix alters the crypto engine and adds in new optimizations for CPUs that have capable instruction sets. There is a risk that this new crypto code is erroneous. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1881107 Title: zfs: backport AES-GCM performance accelleration To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/zfs-linux/+bug/1881107/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
