Lora E32 TTl 100 arduino : How to improve transmission time?

[tdv6net]

Hi, I have two lora E32 TTL 100 modules but when I run tests, I get a trasmission time around 2s.
In order to drive my robot, I would like it to be around 100µs.
Do you have any ideas of code ou parameters I could use ?
Thanks

Receiver code :

  if (loraSerial.available() > 0) {
    String input = loraSerial.readString();
    Serial.println(input);
  }

Transmitter code :

 if (Serial.available() > 0) {
    String input = Serial.readString();
    loraSerial.print(input);
}
