Snapman集合了TCC编译器可以直接编译执行C语言脚本，其脚本执行效率和C#编译程序进行效率对比，包括下面4方面：
1、函数执行效率
2、数字转换成字符串
3、字符串的叠加
4、MD5算法
这是C#代码：

这是Snapman页面：
两种代码的设计和实现方法完全一样，其运行结果对比：
C#执行结果：
Snapman执行结果：
结论：
1、函数执行C#要比Snapman慢一些
2、数字转换C#要比Snapman慢一倍多
3、字符串叠加C#使用了最高效的StringBuilder，执行速度和Snapman差不多
4、执行Md5算法，C#就要比Snapman慢了11倍
所以Snapman的脚本运行速度是非常快速的。
