WINDOW7 Optimization: ReadyBoost Summary

Windows Vista above system carries the ReadyBoost function, in the physical memory and the virtual memory establishes a layer of cache, the cache page Exchange size is 4k-512k, the small file random access speed is much faster than the mechanical disk, therefore when needs to use the virtual memory, You can feel a great improvement in performance.

And if the physical memory space is large enough, ReadyBoost is useless?

When the physical memory is large enough, it only indicates that the second program is running, it is possible not to call to virtual memory, which is related to the running of Third-party software. The core function of Windows is to use the paging file system, while the virtual memory is turned off, which is equivalent to shutting down the paging file system, while the third party software that requires virtual memory is not functioning properly.

If the program needs to use a paging file system, even if the physical memory is large, ReadyBoost still have the effect of accelerating the system, but the space for Ascension is not much.

If the computer disk is a solid-state drive, its access speed is far superior to the external flash drive, this time ReadyBoost will not have the effect of accelerating the system, but will make the system slow.
