Webbench是一个在linux下使用的非常简单的网站压测工具。它使用fork()模拟多个客户端同时访问我们设定的URL，测试网站在压力下工作的性能，最多可以模拟3万个并发连接去测试网站的负载能力。Webbench使用C语言编写, 代码实在太简洁，源码加起来不到600行。
Webbench is a very simple to use under linux Website pressure measurement tool. It uses the fork () to simulate multiple clients simultaneously access performance URL, test site work under pressure we set up to simulate the load capacity of 30,000 concurrent connections to test the site. Webbench using the C language, the code is too simple, not add up to 600 lines of source code. (2016-01-09, Unix_Linux, 30KB, 下载1次)

在linux环境下编写一个控制台应用程序，程序中有一个共享的整型变量shared_var，初始值为0；创建一个线程并使其立即与主线程并发执行。新创建的线程与主线程均不断地循环，并输出shared_var 的值。主线程在循环中不断地对shared_var 进行加1操作，即每次循环shared_var 被加1；而新创建的线程则不断地对shared_var 进行减1 操作，即每次循环shared_var 被减1。观察程序运行的结果，并对你看到的现象进行解释。
In the Linux environment. Write a console application, in the program have a Shared shared_var integer variables, the initial value of 0 Create a thread and make it with the main thread immediately execute concurrently. The newly created thread and the main thread are continuously circulation, and the value of output shared_var. The main thread in a loop to add 1 shared_var continuously operating, namely each loop shared_var added 1 While the newly created thread continuously to minus 1 shared_var operation, namely each loop shared_var was minus 1.
