If you're on loopback and you'd like to close that gap, you need to turn
on SIO_LOOPBACK_FASTPATH. I've no idea if ASIO can do that for you, I'm
still on a pre-churn ASIO. An alternative is to bind to a real NIC, and
not go via loopback.
No sure to follow. Loopback only allows local (same host) connection, no?
What do you mean bind to a real NIC? That actual DHCP allocation IP?
If you're on a real NIC over a real network, I find a 20-30ms connection
time abnormal. Windows 10 has a fast TCP stack, compared to previous
Windows. It should be single digit milliseconds.
Yes to both. Not sure how to diagnose this further though. --DD
