ESPs are not communicating on TCP protocol.
Using ESP-NOW the communication, as Francesco says, is rapid.
Have not tried it yet. I have no experience on the ESP modules and need some reading before I understand how to do any flashing, connecting etc.
I have two ESP8266 modules from Ai and hopefully will soon put it on the breadboard.
