It all depends how you connect to your node. If you just use your IP it will be fast as hell. If you use VNP wireguard will be very fast too. If you behind TOR u sacrifice some speed and stability, but neverless my payments go through 10 sec very max and on average between 2 and 5 seconds. Depend also if the route is already know.

And of course if you have shitty ADSL (so bad upload) and family always using internet at home, don't think about it.
