This is standard textbook stuff. Read Cisco press's 'Deploying License

Using the same channel is bad, because the APs will interfere with each 
other and your throughput will be reduced. Imagine if you have a total 
of 2 APs with 10 clients each, the bandwidth will have to be shared 
amongst the 22 devices. So, if you're able to get 54Mbps on that 
channel, the net result is everybody gets 54/22 = 2.45Mbps each. Not a 
very pretty sight.

Roaming with multiple APs on the same channel is OK for small set ups.
