If all the data fits in the cache, then the data is read from disk only once; after that, all requests are satisfied from the cache at memory speed.
如果所有数据都在缓存中，那么只需从磁盘读取一次数据；毕竟，所有的请求都可以用内存速度从缓存中得到满足。
The path from the system processor/memory/OS/App to the HBA contains only the read data block.
在从系统处理器/内存/操作系统/应用程序到HBA 的路径上，只传输读取数据块。
For example, when Axis2 is mediating messages, and if it needs to read only the headers of the SOAP messages, AXIOM prevents it from reading the whole SOAP message, making it highly memory efficient.
例如，当Axis2作为中介传递时，如果需要仅读取SOAP消息的Header,AXIOM将防止其读取整个SOAP消息，使其具有很高的内存效率。
All motherboards include a small piece of Read Only memory (ROM) which is separate from the main system memory used for loading and running software.
