20ms

I like the Visa ad played on Moneybox on radio 4.  Visa boasted that they process transactions in 20ms which is 7 times faster than their competition.  Well I'm convinced.  Who would want to have to wait for 0.14 seconds for a transaction to go through when they could wait 20ms with Visa.  If they could now tackle the queues for the checkouts where i have to wait on average 10 mins I would be very grateful.
