Awww, what a little cutie that Justin is.

But...can he turn over 464 transactions in 4 minutes ?

Take a look at these 2 blocks from NXTs blockchain:
Blocks 417719 and 417720 both contain a payload of 232 transactions each.....which is 464 tx in 240 seconds, without a hiccup.
This is one of the reasons why NXT is holding so well compared to the rest of the alt-coin market:
NXT technology is solid, and is actually being used right now.
