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