What:		/sys/kernel/uids/<uid>/cpu_shares

Description:

		The /sys/kernel/uids/<uid>/cpu_shares tunable is used

		to set the cpu bandwidth a user is allowed. This is a

		propotional value. What that means is that if there

		are two users logged in, each with an equal number of

		shares, then they will get equal CPU bandwidth. Another

		example would be, if User A has shares = 1024 and user

		B has shares = 2048, User B will get twice the CPU

		bandwidth user A will. For more details refer
