Java下AES加密性能測試速度爲280MB/s

測試目的

測試Java下的AES的加密速度。

測試環境

• 機器1：

  • 硬件：i5 9600K + 16 GB DDR4 2666 + 512GB Intel 760P NVME
  • 軟件：Window 10 + Java 1.8.0_251

• 機器2：

  • 硬件：i7 6500K + 8 GB DDR4 2666 + 1T機械硬盤
  • 軟件：Window 10 + Java 11.0.7

測試結果

根據以下測試結果，在第1次虛擬機熱身後，機器1的加密速度可以達到 280MB/s 左右，機器2可以達到130 MB/s - 170 MB/s。
