If you are going to use N threads for N clients in the server app, it can use N channels, however, if amount of time it takes to calculate the result is larger than it is to push data down the network, 1 channel can work perfectly fine. In any case, you probably can get 80% of work done with just 1 channel and then switch to N. 

Opening a channel results in a network round trip between your app and AMQP broker but most apps probably can consider this "a lightweight operation".
