It's called 3-way handshake, so it is transmitted three times: SYN -> SYN/ACK -> ACK. The minimum time required is two 1.5 times the round-trip time (RTT).

(Each side sees a 1x RTT delay for the handshake to happen while the server is one transmission delay / .5 RTT behind the client - assuming equal transmission delay for both directions.)

In your capture, the only transmission time is between SYN and SYN/ACK. The successive ACK is the reaction to the received SYN/ACK. The socket is established on this side and the local node fires away with GET.

On the client side, the sequence is

  1. SYN sent
  2. longer delay (RTT + remote stack overhead) - 0.020003
  3. SYN/ACK received
  4. very small delay (local stack overhead) - 0.000077
  5. final ACK is sent, socket is open
  6. very small delay (local stack & application overhead) - 0.000223
  7. GET sent

On the listener (server) side, this would look like

  1. SYN received
  2. very small delay (local stack overhead)
  3. SYN/ACK sent
