学习.Net Remoting已有一段时间,对于其初步部署应该倒不是很难,真正应用到系统中则需要考虑的问题逐渐多了起来,.Net Remoting机制其特点可以穿透防火墙,在局域网内速度很快,实现证明是比Web Service快很多,但在广域网测试的时候.Net Remoting(使用TCP)效能明显不如Web Service运行效能,后来通过更改.Net Remoting协议改为HEEP+SOAP方式进行,效能有所改善,网络上很多资料显示Web Service效能明显比.Net Remoting效能快,但个人觉得实用为第一,不必要追求所谓真正的快速,因为没有绝对的快速!
选择机制要考虑到使用范围,开发环境还有网络配置等等因素,选择适合的才是最重要的!
在这次.Net Remoting效能改善最大的感受是,尽量少进入通道,尽量一次性读取必要讯息,重复使用离线数据源,并且使用了数据压缩技术,根据网络上的资料修改所得,与大家分享!
使用之前需要下载组件: ICSharpCode.SharpZipLib 类库可以从这里下载。
