| 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 | |
