Q: What is Fair Share CPU Scheduling?

A:In OSs prior to Windows Server 2008 R2, any user could make use of the full resources of a Remote Desktop Session Host. When resources were available,this relaxed distribution of resources didn't create a problem; however, when resources became scarce, the actions of one user could consume resourcesthat were needed by others.

The Fair Share CPU Scheduling feature in Windows Server 2008 R2 reduces the effect of users who make heavy use of resources by distributing processortime equally across the number of active sessions. With this feature in Server 2008 R2, the actions of one user can't affect the performance of thesystem for others, even under high load.
