480K TPS would be a wonderful problem to have but in the meantime I think this sort of transaction volume has a limited number of contestants. Just how many companies do work at netflix, google or amazon scale? Not many.The thing to remember is that evil Big-O notation from those college days. Adding the fewest LOC could cause the 480K to fall like a rock. Every bit of work you ask the transaction to perform could have a drastic effect.For example; let’s say that the 480K is just counting the number of transactions… nothing else. If you decided to add the number a second time then you’d also expect the TPS rate to be half. This becomes more relevant when that “second” thing is much more costly.
