前言 将文件从一台计算机同步或备份到另一台计算机的快速简便的方法是使用rsync.我将介绍通常用于备份数据的命令行选项,并显示一些选项以极大地将传输速度从大约20-25 MB / s加快到90 MB / s以上! rsync的简短描述 rsync协议能够有效地在计算机之间同步文件.它仅通过传输更改的文件来完成此操作,除此之外,它还尝试仅传输本地文件和远程文件之间的差异,以进一步最小化传输的数据大小.底层数据传输使用Secure Shell或  SSH保护,这增加了另一层计算开销来安全地加密数据,…

小结: 1. 小文件存储于一个文件中: 在内部,磁盘缓存(disk cache)实现了它自己的一组数据结构, 它们被存储在一个单独的缓存目录里.其中有索引文件(在浏览器启动时加载到内存中),数据文件(存储着实际数据,以及HTTP头以及其它信息).比较有趣 的是,16KB以下的文件存储于共同的数据块文件中(data block-files,即小文件集中存储于一个大文件中),其它较大的文件才会存储到自己专属的文件中.最后,磁盘缓存的淘汰策略是维护一个LRU,通 过比如访问频率和资源的使用时间(age…

看U3D文档,心得:对于3D场景,使用分层次的距离裁剪,小物件分到一个层,稍远时就被裁掉,大物体分到一个层,距离很远时才裁掉,甚至不载.中物体介于二者之间. 文档如下: Good performance is critical to the success of many games. Below are some simple guidelines for maximizing the speed of your game’s rendering. Locate high graphics i…
