测试环境(PC1装了N多软件,响应相当慢)

PC1  Win7 32                         Intel 2.10GH双核            内存2G          NAT

PC2  Windows Server 64     Intel Xeon 2.50GHz 24核内存16G       公网IPxxx.xxx.xx.xxx

 

Test11(延迟): PC1两进程互传

URPipe:不可靠模式双向管道
RPipe:可靠模式双向管道
mcast:组播(JxtaMulticastSocket)
socket:基于流的接口(JxtaServerSocket/JxtaSocket,对本项目影响不大,由于时间关系,没有进行测试)
单位:毫秒;表格中的数值是RTT(Round Trip Time)往返时间,计算单程时间减半。
 
Test11是在PC1上的两进程互传,可以近似看做是在同一个局域网中。
其中URPipe的时间明显小于RPipe的时间,但比起Tcp和Udp仍然较大。
比较出乎意料的是mcast,其RTT值将近3秒,这个以前没有注意过。
 
Test12是从PC1向PC2发送消息,然后PC2在收到消息后马上将消息返回给PC1所消耗的时间。测试结果与Test11基本相同,除了各项数值普遍要大一些。
 
另外一个现象值得注意:
在PC1上,对于双向管道,当使用连续密集发送100消息,延迟会逐渐增大到1s以上而使用不可靠模式时,丢包现象比较严重,发了100个消息,最后只收到40个消息。
在PC2上,对于双向管道,当使用连续密集发送100消息,延迟只增大到100ms级;而且使用不可靠模式时,基本没有丢包现象。
看来我的电脑确实该扔了。。。
 
——————————————————————————————————————————————————
 
感觉延迟虽然会对系统有一定影响,但还不是最关键的因素,对于流媒体来说,一定程度的延迟是可以接受的。
上面的测试结果可以作为参考,由于测试过程比较随意,因此不是很精确。
本来想多次发消息取平均值可能更科学一些,但在PC1上连续发消息很多次后,延迟很快增长到若干秒,感觉失去了测试的意义,就此作罢。。。

好吧,针对连续密集发送,可能之前的测试代码有问题,做如下改进后,看来好了很多
1 在循环外分配内存(原来在循环内分配内存)
2 每次发送消息后线程休眠100ms
下面是测试结果(可靠双向管道每次只发送1字节数据,第一列是序号,第二列是RTT)
