TCP throughput?

[Masateru KUWATA]

Dear

I am testing tinc on Windows and found some interesting behavior.

I used "TCPOnly" parameter for both end because I wanted to go through
NAT. However, by using TCPOnly parameter, the response of PING slowed
down significantly.

The PING response with UDP is about 4ms, but it bumped up to 2000ms with
TCP.

I am just curious whether this is caused by using TCP.
