| 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 |
