5 Description:
6                 The /sys/kernel/uids/<uid>/cpu_shares tunable is used
7                 to set the cpu bandwidth a user is allowed. This is a
8                 propotional value. What that means is that if there
9                 are two users logged in, each with an equal number of
10                 shares, then they will get equal CPU bandwidth. Another
11                 example would be, if User A has shares = 1024 and user
12                 B has shares = 2048, User B will get twice the CPU
13                 bandwidth user A will. For more details refer
