我正在运行一个简单的演示，它使用Java zookeeper客户端连接zookeeper服务器。在windows上连接成功需要很长时间（至少10秒钟），但在Linux上连接成功非常快。原因是什么，如何处理？

软件版本：

操作系统：Windows 11有两个虚拟机，一个是Ubuntu服务器，另一个是Ubuntu桌面，
Java：OpenJDK 11，
zookeeper服务器：版本3.7.0，部署在Ubuntu虚拟机上
演示代码：

public static void main(String[] args) throws Exception {
    log.info("begin connect to zookeeper ================================>>");
    ZooKeeper zooKeeper = new ZooKeeper("192.168.1.16", 30000, watchedEvent -> {
    });
    log.info("connect zookeeper success =================================>>");
    zooKeeper.close();
    log.info("zookeeper is closed...");
}

结果和日志：

为了减少字数，我省略了一些无用的日志，从日志时间可以看出，从连接到结束需要很长时间（见'=>>'标志）。

可以看到连接zookeeper和关闭连接是立即完成。
