AES-GCM解密慢度JAVA

Question

我正在尝试使用JDK 1.11.0.6在AES-GCM模式（cipherinputstream）中解密50mb文件，它需要9分钟，而在CTR模式下则需要10s，我在这里错过了什么吗？ CTR和GCM模式下的加密仅需600毫秒左右

我看过较早的帖子， Java 9: AES-GCM performance

我尝试使用JDK 1.8、1.9、1.11.0.6甚至是1.13。

令人惊讶的是，JDK 1.9耗时3分钟，而其他所有耗时约9-10分钟，与CTR模式下的10s相比绝对不可接受。

与Bouncy Castle Provider相同的代码将在700毫秒内解密。 BC实现与Native Java实现之间的差异如此之大？

示例代码

public static void encryptfile() throws NoSuchAlgorithmException, NoSuchPaddingException, InvalidKeyException, InvalidAlgorithmParameterException, IOException {
    InputStream fin = new FileInputStream("test.txt");
    OutputStream fout = new FileOutputStream("enc_test.txt");
    SecretKeySpec serverKey = new SecretKeySpec(HexConverterUtil.BASE16_DECODE("a4e97a4713841586ca639a416c636e3ef2a404efaf58b0a7768cd5758b1297a0"), "AES");
    GCMParameterSpec gcmParameterSpec = new GCMParameterSpec(16 * 8, HexConverterUtil.BASE16_DECODE("258f7d4c1c72bee0109bcbe5"));
    Cipher encryptCipher = Cipher.getInstance("AES/GCM/NoPadding");
    encryptCipher.init(Cipher.ENCRYPT_MODE, serverKey, gcmParameterSpec);
    fout = new CipherOutputStream(fout, encryptCipher);

    byte[] bytesBuffer = new byte[4096];
    int bytesRead = 0;

    while ((bytesRead = fin.read(bytesBuffer)) != -1) {
        fout.write(bytesBuffer, 0, bytesRead);
    }
    fin.close();
    fout.close();
}

public static void decryptfile() throws NoSuchAlgorithmException, NoSuchPaddingException, InvalidKeyException, InvalidAlgorithmParameterException, IOException {
    InputStream fin = new FileInputStream("enc_test.txt");
    SecretKeySpec serverKey = new SecretKeySpec(HexConverterUtil.BASE16_DECODE("a4e97a4713841586ca639a416c636e3ef2a404efaf58b0a7768cd5758b1297a0"), "AES");
    GCMParameterSpec gcmParameterSpec = new GCMParameterSpec(16 * 8, HexConverterUtil.BASE16_DECODE("258f7d4c1c72bee0109bcbe5"));
    Cipher decryptCipher = Cipher.getInstance("AES/GCM/NoPadding");
    decryptCipher.init(Cipher.DECRYPT_MODE, serverKey, gcmParameterSpec);
    fin = new CipherInputStream(fin, decryptCipher);

    OutputStream fout = new BufferedOutputStream(new FileOutputStream("dec_test.mp3"));

    byte[] bytesBuffer = new byte[4096];
    int bytesRead = 0;

    while ((bytesRead = fin.read(bytesBuffer)) != -1) {
        fout.write(bytesBuffer, 0, bytesRead);
    }
    fin.close();
    fout.close();
}
