Question

我已经在VPS（OVH）上部署了一个Jhipster应用程序，并在其上安装了tomcat7。几天后，应用程序似乎非常缓慢。一旦我启动tomcat，我会做一个netstat -tanpu，我得到了这些连接：

我想知道我的问题是否与127.0.0.1:3306和xx.xx.xxx.xxx:8080（java和mysqld）的许多连接有关

Answer 1

有一个连接池，因此您可以打开多个连接而不会导致任何特定问题。

您可以在＆＃34;监控＆＃34;中检查连接池的状态。屏幕，当然你可以运行JConsole来获得更详细的信息（我们使用的是HikariCP，它通过JMX导出大量数据）

Jhipster消耗大量资源
