What: /sys/kernel/uids//cpu_shares Date: December 2007, finally removed in kernel v2.6.34-rc1 Contact: Dhaval Giani Srivatsa Vaddagiri Description: The /sys/kernel/uids//cpu_shares tunable is used to set the cpu bandwidth a user is allowed. This is a proportional 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.
