The figures for the bitcoin blockchain are public and monitored by most exchanges. They are at about 11000 transactions/hour[0] - ~3 transactions/second for the entire world.

The lightning network is a separate system for transactions denominated in bitcoin. It does nothing to modify the capacity of the bitcoin network, it creates a way to do transactions WITHOUT using the bitcoin network (except occasionally).
