带组装8ROS_512通道测试结果

原有的读出方式不变，一个ROS处理多个socket, 每次read之前先select检查通道是否有数。

发送端控制发送频率为1KHz。

8ROS布置在一个服务器cmm03node03上，每个ROS接收64个通道的数据。每个ROS一个RequestHandler, 一共有四个SFI。接收端和发送端的socket buffer size 都设置为8MB。得到的测试结果如下：

1. 平均事例率：919.5Hz， 总带宽：919.5*2*8*64*8/1024/1024=7.18Gb/s.

2. 此时ROS所在的服务器的CPU占用率为: CPU 的 idle 为 5%。
