I timed the flow of each using my trusty old 10 liter bucket. The 1/2" valve on the old barrel on the left is a globe type and takes 85 seconds to fill the bucket, so that's 7 liters (1.85 US gallons) per minute. The barrel on the right has a newer 1/2" ball valve and takes 65s to fill the bucket (9.2l/2.4USgal per minute). When both are open, the common 3/4" ball faucet fills it in 50 seconds, giving a flow of 12 liters (3.2 US gallons) per minute. That's 70% faster than the just the old barrel, plus twice the volume of rain water

I did the test with the barrels 90% full. Of course, the lower the water level, the slower the flow. The maximum head (distance from faucet to overflow hose at top) is about 78cm (31in.)
