If you use

As our website and project needs, as well as the cost of the VPS host/server continuously reduced, more and more webmaster users will choose the VPS or server as our site environment, but for users, most of the basic operations from the online tutorials, For example, use SSH software to log in and then learn the tutorial installation panel, a key package, and then go to build the site.

Linux implementation of the request page scheduling, page scheduling is to say that the page from the hard disk on-demand exchange come in, when no longer need to exchange out. This allows the virtual address space of each process in the system and the total amount of actual physical memory to be no longer directly linked, since the swap space on the hard disk can give the process an illusion of almost infinite physical memory. The exchange is transp
