This is a 8*3e42d1deSCarlos Bilbao proportional value. What that means is that if there 93b82a112SWang Long are two users logged in, each with an equal number of 103b82a112SWang Long shares, then they will get equal CPU bandwidth. Another 113b82a112SWang Long example would be, if User A has shares = 1024 and user 123b82a112SWang Long B has shares = 2048, User B will get twice the CPU 133b82a112SWang Long bandwidth user A will.
