This is a 8*3e42d1deSCarlos Bilbao proportional value. What that means is that if there 90594fe06SDhaval Giani are two users logged in, each with an equal number of 100594fe06SDhaval Giani shares, then they will get equal CPU bandwidth. Another 110594fe06SDhaval Giani example would be, if User A has shares = 1024 and user 120594fe06SDhaval Giani B has shares = 2048, User B will get twice the CPU 130594fe06SDhaval Giani bandwidth user A will.
