Yes of course, the encryption process is slower than the disk access, so 
encryption will eat 100% cpu while transfering data from/to an encrypted 
disk device.

Especially if you copy from one encrypted device to another, so the data 
also has to be decrypted first.

Did you expect anything else?

Greetings,

  Gunter
