我正在尝试使用AES/GCM/NoPadding加密和解密数据.我安装了JCE Unlimited Strength Policy Files并在下面运行了(简单的)基准测试.我使用OpenSSL做了同样的事情,并且能够在我的PC上实现超过1 GB/s的加密和解密.

使用下面的基准测试,我只能在同一台PC上使用Java 8进行3 MB/s的加密和解密.知道我做错了什么吗？

public static void main(String[] args) throws Exception {
    final byte[] data = new byte[64 * 1024];
    final byte[] encrypted = new byte[64 * 1024];
    final byte[] key = new byte[32];
    final byte[] iv = new byte[12];
    final Random random = new Random(1);
    random.nextBytes(data);
    random.nextBytes(key);
    random.nextBytes(iv);

    System.out.println("Benchmarking AES-256 GCM encryption for 10 seconds");
    long javaEncryptInputBytes = 0;
    long javaEncryptStartTime = System.currentTimeMillis();
    final Cipher javaAES256 = Cipher.getInstance("AES/GCM/NoPadding");
    byte[] tag …

我RestTemplate在java中使用spring 编写REST客户端,在使用'HTTPBuilder'时使用groovy 编写REST客户端.两次调用都在我的电脑上花了10秒钟.在Postman和其他工具中,这种相同的帖子请求需要300毫秒.

这是groovy脚本中的简单调用.必需是间BEGIN REST invocation和END REST invocation:

    @Grapes(
            @Grab(group='org.codehaus.groovy.modules.http-builder', module='http-builder', version='0.7')
    )


    import groovy.json.JsonOutput
    import groovy.json.internal.LazyMap
    import groovy.transform.ToString
    import groovyx.net.http.HTTPBuilder

    import static groovyx.net.http.ContentType.JSON
    import static groovyx.net.http.Method.POST


    HTTPBuilder http = new HTTPBuilder()

                                                    ,new Flight(departureStation: "CRL", arrivalStation: "WAW", date: new Date(2018, 10, 26))])

    def jsonRequest = JsonOutput.toJson( forechart …
