The results are similar to mine, but slightly worse, but this is certainly due to the size of the encrypted packet. Because as mentioned in my previous message, the larger the packet to be encrypted, the less efficient it is (that’s what I see).

Also If I understand your are not testing with “Nitrokey HSM 2”.
