B4R Question ESP8266

I send from my android device to a microcontroller and this sends some data back as confirmation.

I use a ESP8266 that receives Wifi data with a server socket and sends it by serial communication to my microcontroller.
The communication between the ESP and uC is 115200 baud.

I used to do this with a bluetooth-serial device on 9600 but this was faster.

Maybe the ethernet socket communication is a lot slower but I think it is also slower because the ESP receveives the complete package, then sends it to the uC. The answer is recieved fully and forwarded to the Android device.

Is it possible that the esp does not wait for the full receipt but just sends byte by byte from port to port?

Or do you think the ethernet is the slowest part.....?
