如何提高弹簧靴的一致性

我有一个要求,创建一个产品,应支持40并发用户每秒(我是新的并发工作)

为了实现这一点,我尝试开发了一个helloworld spring boot项目。 即。,

弹簧防尘套(1.5.9)

具有get端点的rest控制器

代码如下:

@GetMapping
public String index() {
    return "Greetings from Spring Boot!";
}

在Gen10 DL360计算机上运行的应用程序

然后我尝试使用apachebench进行基准测试

从上面的测试运行来看,我达到了每秒约27K的速度,本身就有75个用户,但这看起来增加了用户数,同时也增加了延迟。此外,我们可以清楚地注意到连接时间正在增加。

我要求我的应用程序支持40k个并发用户(假设所有用户都使用各自的浏览器),请求应该在250毫秒内完成。

请帮帮我
