memory read request的意思|示意

Therefore, read events that request data already stored in memory don't generate a trip to the hard disk.

因此，请求存储在内存中的数据的读事件不会访问硬盘。

A web server that is storing an object in memory will likely respond to a request faster than a web server that needs to read the file from disk.

在内存中存储某个对象的Web服务器可能会比其他需要从磁盘读取文件的Web服务器更快地响应一个请求。

This allows the entire lookup table to be loaded into memory each time a user submits a request to read or write data.

在用户每次提交一个读写数据的请求时，这可以将要查询的整个表装入内存中。

If you process a request in a different thread which is running in another process context, you would not be able to read user mode memory across process boundaries.

如果你处理一个不同线程的请求，而这个线程却又运行在另外一个进程的上下文中，你也许不能正常的跨越进程分界线来读取用户态内存。
