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 | ||
