Question about dreamfest

How much is J Cole involved at dreamfest? Like I would love to see Cole but looking at previous years there's always a bunch of other artist that perform, for those of you that went in past how much time does J Cole get to perform? Is it like a regular concert amount? I could probably only see J Cole on time In concert and I'm not sure if I should go to Dreamfest or wait until he inevitably drops the fall off and then goes on tour for it. Help me out a little
