测试代码

package com.litongjava.tio.http.server;

import java.io.IOException;

import com.litongjava.tio.http.common.HttpConfig;
import com.litongjava.tio.http.common.handler.HttpRequestHandler;
import com.litongjava.tio.http.server.controller.IndexController;
import com.litongjava.tio.http.server.handler.HttpRoutes;
import com.litongjava.tio.http.server.handler.SimpleHttpDispatcherHandler;
import com.litongjava.tio.http.server.handler.SimpleHttpRoutes;
import com.litongjava.tio.server.ServerTioConfig;

public class MainApp {

  public static void main(String[] args) throws IOException {
    // 手动添加路由
    IndexController controller = new IndexController();
    HttpRoutes simpleHttpRoutes = new SimpleHttpRoutes();
    simpleHttpRoutes.add("/plaintext", controller::plaintext);

    // config server
    HttpConfig httpConfig = new HttpConfig(80, null, null, null);
    // 关闭心跳
    HttpRequestHandler requestHandler = new SimpleHttpDispatcherHandler(httpConfig, simpleHttpRoutes);
    HttpServerStarter httpServerStarter = new HttpServerStarter(httpConfig, requestHandler);
    ServerTioConfig serverTioConfig = httpServerStarter.getServerTioConfig();

    serverTioConfig.setHeartbeatTimeout(0);
    // start server
    httpServerStarter.start();
  }

}

package com.litongjava.tio.http.server.controller;

import java.util.HashMap;
import java.util.Map;

import com.litongjava.tio.http.common.HttpRequest;
import com.litongjava.tio.http.common.HttpResponse;
import com.litongjava.tio.http.server.util.Resps;

public class IndexController {
  public HttpResponse plaintext(HttpRequest request) {
    return Resps.txt(request, "Hello, World!");
  }
}

代码含义：
启动Http服务器
对外提供1个接口,"plaintext"

测试过程
启动服务端

java -jar target\tio-server-study-1.0.jar

模拟10个并发，十万次访问：

ab -c10 -n100000 http://localhost/plaintext

这是一个使用ApacheBench进行的性能测试报告，主要测试了服务器在并发访问下的性能。下面是对报告的一些关键指标的解释：

Concurrency Level: 并发用户数，这里是10个。
Time taken for tests: 所有请求完成所需的总时间，这里是235.745秒。
Complete requests: 完成的请求总数，这里是100000次请求。
Failed requests: 失败的请求总数，这里是0，表示所有请求都成功了。
Requests per second: 平均每秒的请求数，这里是424.19次/秒。
Time per request: 用户平均请求等待时间，这里是23.574毫秒。
Transfer rate: 服务器的平均传输速率，这里是57.58KB/sec。

在"Connection Times"部分，给出了连接、处理和等待的时间统计信息，包括最小值、平均值、中位数和最大值。

在最后的百分比部分，列出了所有请求中有多少百分比的请求可以在特定的时间内完成。例如，50%的请求在2毫秒内完成，98%的请求在399毫秒内完成，最长的请求需要19330毫秒才能完成。
