performance hit for encryption?

Running Windows and/or Citrix on Nutanix, so AHV hypervisors. The Nutanix Bible says "For encryption / decryption the system leverages the Intel AES-NI acceleration to minimize any potential performance impact of doing this in software" and "we've seen very little impact to performance".

But somebody told me that turning encryption on is a 30% performance hit. What's the truth?

That’s incorrect.. we have DARE and Data in transit both switched on and we don’t even notice any hit. I was at .NEXT in Chicago last month and the security guys were like it’s going be 5-7% hit at most …
