使用 KeepAlive 优化 Camel HTTP4

Question

我希望能够 POST 使用 Camel 以非常快的速度（> 1500/秒）向 HTTPS 服务器发送消息，仅使用一个到服务器的连接。

我尝试将 keepAlive 设置为 true，但我仍然看不到速度有任何改善。

在发送 5 条消息时进行了 tcpdump，我在 wireshark 上发现了 5 SYN/ACK 个数据包。可能 SSL 证书也在每个 POST 上发送。（tcpdump 捕获了 102 个数据包，但我发送的只是 5 "HelloWorld" 个字符串）

有什么办法可以加快速度吗？这是我使用的代码：

    CamelContext context = new DefaultCamelContext();
    final HttpComponent http = (HttpComponent) context.getComponent("https4");

    http.setConnectionsPerRoute(1);
    http.setMaxTotalConnections(1);
    HttpConfiguration httpConfiguration = new HttpConfiguration();
    http.setHttpConfiguration(httpConfiguration);;

    context.addComponent("fcpHttpComponent", http);
    template = context.createProducerTemplate();

    headers.put(Exchange.CONTENT_TYPE, "application/json");
    headers.put(Exchange.HTTP_METHOD, HttpMethods.POST);
    final String endpoint = "https://xxx.xxx.xxx.xxx:443"; 

    try {
        httpEndpoint = new HttpEndpoint(endpoint, http, new URI(endpoint));
        httpEndpoint.configureProperties(headers);
        PoolingHttpClientConnectionManager clientConnectionManager = new PoolingHttpClientConnectionManager();
        SocketConfig socketConfig = SocketConfig.custom()
                .setSoKeepAlive(true)
                .setSoReuseAddress(true)
                .setTcpNoDelay(true)
                .setSndBufSize(10)
                .build();
        clientConnectionManager.setDefaultSocketConfig(socketConfig);

        HttpClientBuilder clientBuilder = HttpClientBuilder.create();
        clientBuilder.setMaxConnPerRoute(1);
        clientBuilder.setConnectionManager(clientConnectionManager);
        clientBuilder.build();
        ConnectionKeepAliveStrategy keepAliveStrategy = new DefaultConnectionKeepAliveStrategy();
        clientBuilder.setKeepAliveStrategy(keepAliveStrategy );
        httpEndpoint.setClientBuilder(clientBuilder);

        httpEndpoint.setClientConnectionManager(clientConnectionManager);

        template.start();
        context.start();
    } catch (final Exception e) {
        LOG.error("Exception while starting Camel context ", e);
    }

    //Call this method 5 times 
    template.asyncRequestBodyAndHeaders(httpEndpoint, message, headers);

SSL 证书详细信息作为 JVM 参数提供。我可以 POST 数据，但速度是我需要改进的地方。

[更新] 我正在使用 Apache Tomcat 8 作为我的服务器。在 server.xml 中设置以下内容：

 <Connector
       protocol="org.apache.coyote.http11.Http11NioProtocol"
       port="443" maxThreads="200"
       scheme="https" secure="true" SSLEnabled="true"
       keystoreFile="/x/store.jks" keystorePass="y"
       clientAuth="false" sslProtocol="TLS" maxKeepAliveRequests="-1" keepAliveTimeout="-1" />

我的服务器还需要配置什么吗？

知道它与 netty4Http 组件一起使用了。这是一些示例代码：

private DataWriter() {
this.context = new DefaultCamelContext();
try {
    final NettyHttpComponent nettyHttpComponent = this.context.getComponent("netty4-http",
            org.apache.camel.component.netty4.http.NettyHttpComponent.class);
    this.context.addComponent("nettyhttpComponent", nettyHttpComponent);
    this.template = this.context.createProducerTemplate();
    this.headers.put("Content-Type", "application/json");
    this.headers.put("CamelHttpMethod", "POST");
    String trustCertificate = "&ssl=true&passphrase=" + "123456" + "&keyStoreFile="
            + "C:/Users/jpisaac/certs/publicKey.store"
            + "&trustStoreFile=C:/Users/jpisaac/certs/publicKey.store" ;

    this.endpoint = "netty4-http:"+ "https://xx.xx.xx.xx:8443/server"
            + "?useByteBuf=true&disableStreamCache=true&connectTimeout=30000&requestTimeout=30000&reuseChannel=true"
            + "&keepAlive=true&tcpNoDelay=true&sync=false&reuseAddress=true&sendBufferSize=1000"
            + trustCertificate;
    this.template.start();
    this.context.start();
} catch (final Exception e) {
    LOG.error("Exception while starting Camel context ", e);
}
}

 public void sendData(final String message) {
try {
    CompletableFuture<Object> future=this.template.asyncRequestBodyAndHeaders(this.endpoint, message, this.headers);
    System.err.println("Sent data "+message);
} catch (final CamelExecutionException e) {
    LOG.error("Error while sending data", e);
}
}
