通过inotify工具和统一获得更好的性能. [英] Gaining better performance with inotify-tools and unison.

问题描述

我使用inotify-tools和unison在计算机之间同步文件夹. 因为我有一个很大的文件夹要同步，所以我只需编写一个inotifywait脚本即可自动完成该工作. 让inotifywait监视大文件夹的子目录以获得更好的性能是否明智?

I use inotify-tools and unison to synchronize folders between machines. Because I have a large folder to synchronize, I just simply write an inotifywait script to do the job automatically. Is it sensible to let inotifywait to monitor the subdirectories of the large folder to gain a better performance?

推荐答案

如果放弃inotify-tools，并且仅使用unison的本机支持来监视文件夹中的更改，则应该会获得更好的性能.通过使用inotify-tools，然后在发生更改时调用unison，unison必须先"重新查找"更改，然后才能进行同步.您可以改为将行repeat = watch添加到您的统一配置文件中，并且unison将连续运行并在发生任何更改时进行同步.它使用自己的文件观察器实用程序unison-fsmonitor检测到更改，该实用程序直接与统一通信.

You should get better performance if you ditch inotify-tools and just use unison's native support for watching your folders for changes. By using inotify-tools and then calling unison when a change occurs, unison has to "re-find" the change before it syncs. You could instead add the line repeat = watch to your unison profile and unison will run continually and sync whenever there is a change. It detects the change with its own file-watcher utility unison-fsmonitor that communicates directly with unison.
