Section 5.2 says:
produces responses earlier before the handshake completes
It should say:
produces responses after the handshake completes
Located on last paragraph last line of section on page 16. First line states 'not to respond with data until the handshake finishes' which contradicts the last line.
This erratum does not correctly interpret the paragraph.
The sentence is:
"But the potential latency saving from TFO may diminish if the server application
produces responses earlier before the handshake completes."
The text refers to when the server response is available, not when it is sent. If the server data isn't yet available, then there is no message to withhold and therefore no performance penalty in waiting for the handshake to complete.
