    With this new patch series they acknowledge Key Locker usage can result in ~5x slower performance than raw AES-NI usage, but they are aiming Key Locker for dealing with disk encryption. In disk encryption scenarios, the disk throughput performance is more likely to be a bottleneck than Key Locker itself.
