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
