What: /sys/kernel/uids/<uid>/cpu_shares
Date: December 2007
Contact: Dhaval Giani <dhaval@linux.vnet.ibm.com>

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
