In a well-tuned site, this disk offload file fits entirely into the file system cache, and is served out of RAM.
在一个优化的网站上，这个磁盘卸载文件会完全存储在文件系统缓存中，它位于RAM之外。
If you enable disk offload, the entry that would be removed from the cache is copied to the local file system.
如果您启用磁盘卸载，则要从缓存中删除的条目将复制到本地文件系统。
So the file system cache can help there quite a bit to avoid read and write operations on the disk.
所以文件系统缓存可以很大程度上帮助避免对磁盘的读写操作。
Linux, under normal circumstances, USES a system file cache to buffer, read, and write requests from disk.
在一般情况下，Linux使用一个文件系统缓存为磁盘请求进行缓冲和读写。
Simplified tuning and operational maintenance due to the fact that with eXtreme Scale, you do not need to worry about tuning the size of the disk offload file or file system cache performance.
由于使用了eXtremeScale，简化了调优和操作维护，您不需要为调优磁盘负载文件的大小或文件系统缓存性能而担忧。
Memcached is used by many large sites to cache various objects in a distributed memory system, rather than having to read from disk or a database.
许多大型站点都使用memcached在分布式内存系统中缓存各种对象，这样就不需要从磁盘或数据库读取它们。
