Yes of course, the encryption process is slower than the disk access, so=20 encryption will eat 100% cpu while transfering data from/to an encrypted=20 disk device. Especially if you copy from one encrypted device to another, so the data=20 also has to be decrypted first. Did you expect anything else?
