Mycat java进程间超高性能通信服务框架

####特性

   1. 使用共享内存映射的技术，多进程之间数据传递直接操作内存，性能极高

   2. 实现了无锁多进程/多线程读写的逻辑，多个进程可以同时并发读写

   3. HP ZBook笔记本测试，单一队列，两个进程通信，最高高达每秒500万的消息传输，3组进程分别对应3个队列，总和超过1000万每秒消息

####使用方式

	1. 启动 io.mycat.ipc.Reader 创建一个空白队列，等待和读取消息

	2. 启动 io.mycat.ipc.Writer 写入消息

HP ZBook 17上 在Eclipse里启动上述两个进程的测试结果截图

注意，由于Windows任务调度的问题，经常会有Read进程得不到调度而停顿的现象，从屏幕输出可以看到此现象。

####限制

	1. JDK 要求 SunJDK 1.8

####内存格式图
