David Short, an IBM consultant,
claims Windows Vista users should consider 4GB of RAM memory of them want optimum Windows Vista performance.
Short has been beta testing Vista for two years and was at the IBM-oriented Share user group conference Florida last week discussing some of Vista's performance requirements. His XP system has 2GB of RAM, which he calls the "sweet spot" for that operating system, but on Vista, 4GB of RAM may be closer to its "Nirvana”, he said.
That's due in part to Windows SuperFetch, which takes data from the hard drive, stores it in the available RAM and makes it readily accessible to the processor. SuperFetch depends a great deal on user predictability and takes snapshots of user activity. If SuperFetch determines that an application is launched at a particular time, it will have it loaded into the available RAM. With more RAM, there's more caching and better software response, said Short.
