Reduce Execution Time for NextionListen()

First, I love your library!!!

One thing I have noticed is that NextionListen() takes almost 1000ms to execute. Here is the code I'm using in the loop() to calculate the execution time.

    int hz1 = millis();
    myNext.NextionListen();
    Serial.println("NextionListen..." + String(millis()-hz));

NextionListen...975

Is there a way to reduce the execution time for NextionListen?

I'm running on a Arduino Compatable ESP32 at 80MHz

Thanks for any help

I was calculating the NextionListen() incorrectly.

NextionListen() must be almost 0ms if it has not received any command.
The only thing it mostly does is to check if Serial has a command. If bytes are found in Serial, it will start to read them. The time it will take will only be sending time for the number of bytes which is not much.
