How can one parallelize tasks in CTR-AES for maximum performance?
From the diagram on CTR mode

you can notice that there are no dependencies between any of the phases of the pipeline. If you have more than one block-size worth of data, you can process each block-size chunk completely independently of the others by calculating $\mathrm{ciphertext}_i = E(\mathrm{key}, \mathrm{nonce} \, || \, \mathrm{counter}_i) \oplus \mathrm{plaintext}_i$.
