系统缓存

system collapse───系统崩溃

systemically───全身的；系统的；影响全身的；影响身体某系统(尤指神经系统)的

system on a chip───系统芯片

systems on a chip───系统芯片

stomachache───n.腹痛，肚子痛；胃痛

system disk───系统磁盘

system disks───系统磁盘

rationale is this: access to a file system based container goes through the operating system kernel, and the operating system comes with a file system cache to speed up repetitive access to files.───理由是：对基于容器的文件系统的访问要经过操作系统内核，而操作系统带有一个文件系统缓存，可以加快对文件的重复访问。

Now, for normal database operation you do not really have to worry about the file system cache because DB2 implements buffer pools that do the necessary caching already.───现在，对于一般的数据库操作，不必考虑文件系统缓存，因为DB 2实现了缓冲池，这些缓冲池已经做了必要的缓存。

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。

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。

This counter includes paging traffic on behalf of the system cache to access file data for applications.───这个数字包括了系统缓存为访问应用程序文件数据而发生的页面通信量。

Since CLOB inserts use direct writes, the file system cache is not needed and is pure overhead.───因为CLOB插入使用直接写入的方式，所以无需文件系统缓存，而仅有纯开销。

If you're using MyISAM seriously you can also add the size of Operation System cache you would like MySQL to use for your table.───如果你大量地使用MyISAM表，那么你也可以增加操作系统的缓存空间使得MySQL也能用得着。

For DMS device container tablespaces, the operating system does not cache pages in the file system cache.───对于DMS设备容器表空间，操作系统不在文件系统缓存器中缓存页面。

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.
