Smaller-sized configurations will still see a gain when using large pages, but the gain will not be as great as when the database is accessing large amounts of memory. This feature is particularly useful when the Oracle buffer cache is several gigabytes.

These configurations consume network, memory, and CPU resources. In addition, because Oracle Database is a high-performance database management system that effectively uses resources of your Windows computer, it should not also serve as any of the following: Most of the operating system specific procedures described in this chapter enable Oracle Database to reserve more system resources, such as CPU, memory, and disk I/O.

Windows Server operating systems offer considerably fewer tuning adjustments than UNIX.
