進去看以後發現是講四月推出的 Ice Lake，在上面新增的
The introduction of the processor instructions AES-NI and VPCLMULQDQ, that are designed for speeding up encryption, and their continual performance improvements through processor generations, has significantly reduced the costs of encryption overheads.
而他們發表出來的數據說 AES-GCM 的效率直接從 ~23 cycles/byte 降到 0.64 cycles/byte，大約是 35 倍的改進？
More and more applications and platforms encrypt all of their data and traffic. As an example, we note the world wide proliferation of the use of AES-GCM, with performance dropping down to 0.64 cycles per byte (from ~23 before the instructions), on the latest Intel processors.
就算不是 AES-GCM，而是其他的 AES 相關演算法，也是三倍以上的改善：
