所谓虚拟机，就是一台虚拟的计算机。他是一款软件，用来执行一系列虚拟计算机指令。大体上，虚拟机可以分为系统虚拟机和程序虚拟机。大名鼎鼎的VisualBox、VMware就属于系统虚拟机。他们完全是对物理计算机的仿真。提供了一个可以运行完整操作系统的软件平台。程序虚拟机的典型代表就是Java虚拟机，它专门为执行单个计算机程序而设计，在Java虚拟机中执行的指令我们称为Java字节码指令。无论是系统虚拟机还是程序虚拟机，在上面运行的软件都呗限制于虚拟机提供的资源中。JAVA 如何做到跨平台。

Python 接口并发测试详解

性能测试是通过自动化测试工具模拟多种正常、峰值及异常负载条件对系统的各项性能指标进行的测试。负载测试和压力测试都属于性能测试，两者可以结合进行。通过负载测试，确定在各种工作负载下系统的性能，目标是测试当负载逐渐增加时，系统各项性能指标的变化情况。压力测试是通过确定一个系统的瓶颈或者不能接受的性能点，来获得系统能提供的最大服务级别的测试。性能测试的重点是测试在并发条件下服务或系统的瓶颈所在，从而优化相关功能，可能涉及软件及硬件的多方面改进。由此可见，性能测试对整个产品非常重要，甚至可以决定一个产品是否能长久发

JConsole远程连接 与 JMX远程连接

通过JConsole，我们可以查看JVM的内存等使用情况，也可以查看MBean信息，我们一般是源码运行项目，然后直接用JConsole访问本地的java程序，这种情况是不需要做任何改动的，可以直接连接本地java程序。但是如果想JConsole远程连接，就需要添加启动参数，开启远程访问。欢迎指出我的错误！
