tokio rust 是否正在重置 tcp 连接？

Question

I am writing a simple server in rust to understand a bit better async tokyo and tcp connections, there are fifty connections and first they write a hello and then they read, and it seems to work fine but when I go to the resource monitor in windows和 select 我的两个程序我看到连接数开始随着一些奇怪的尖峰而变化。

这是我的服务器

use tokio::{
    io::{AsyncReadExt, AsyncWriteExt},
    net::{TcpListener, TcpStream},
};

#[tokio::main]
async fn main() {
    let listener = TcpListener::bind("127.0.0.1:62000").await.unwrap();
    loop {
        let (socket, addr) = listener.accept().await.unwrap();
        println!("new connection from {}", addr);
        handle(socket).await;
    }
}

async fn handle(mut socket: TcpStream) {
    tokio::spawn(async move {
        let mut buffer = [0; 1024];
        loop {
            socket.write_all(b"hello").await.unwrap();
            socket.read(&mut buffer).await.unwrap();
        }
    });
}

在这里我开始我的客户

use tokio::{
    io::{AsyncReadExt, AsyncWriteExt},
    net::TcpStream,
};

#[tokio::main]
async fn main() {
    let mut handles = Vec::new();
    for _ in 0..50 {
        let mut socket = TcpStream::connect("127.0.0.1:62000").await.unwrap();
        println!(
            "connected to {} from {}",
            socket.peer_addr().unwrap(),
            socket.local_addr().unwrap()
        );

        let handle = tokio::spawn(async move {
            let mut buffer = [0; 1024];
            loop {
                socket.write_all(b"hello").await.unwrap();
                socket.read(&mut buffer).await.unwrap();
                tokio::time::sleep(tokio::time::Duration::from_millis(10)).await;
            }
        });
        handles.push(handle);
    }
    for handle in handles {
        handle.await.unwrap();
    }
}

这是正常行为吗？ 还是我在某个地方搞砸了？
