| 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 |
