There was an instance of SatoshiDice taking up half of a Bcash block consolidating UTXOs the other day. Congestion will happen on Bcash, as will a hard fork to infinite inflation due to lack of transaction fees to supplant block rewards.
I'm talking about Bitcoin Cash. You must be confused "Bcash" is a fork of zcash that hasn't launched yet.
