I recently went through the process of encrypting all the disks in my array. Is it typical to expect a dramatic decrease in performance? I understand that this could happen because of the extra work required but I was under the impression, and based of other Unraid experiences I found on the internet, that with sufficient CPU it should not have that great of an impact. I cannot write faster than 60MB/s, prior to encryption I was usually over 100MB/s. My server is a Dell R530 with 2x Xeon E5-2630 v3. That proc has the features that should be able to handle encryption sufficiently. I even tried messing around with disk tunables to see if I could squeeze more out of it, nothing gets it past 60.
Any insight would be greatly appreciated. Thanks in advance.
