In the UK at least, chip takes about 2 - 3 seconds. 4 or 5 would feel long. Contactless is usually instantaneous; I assume there's more caching involved somewhere.
I haven't seen anyone or myself swiped in about 10 years, and that was only because the chip reader wasn't working at the time.
Contactless transactions for smaller amounts are often offline approved without requesting approval from the bank/network. This takes off the 2-3 seconds of the transaction time.
