Arduino and Wolfram Mathematica dynamic plot

I am very frustrated with the slow transfer of data from the Arduino serial COM port to the PlotLine[] in dynamic function. In the Arduino Plot Serial, data is drawn instantly. But when connected to WM with USB able, the plots are very very slow. About 10 and 20 to 1 speed. The Arduino code is sending a 6 pair of integers in ASCI format. Any suggestions as to how speed up.

He Arduino sketch is this

#include <Wire.h>
#include "Adafruit_AS726x.h"
//create the object
Adafruit_AS726x ams;

uint16_t sensorValues[AS726x_NUM_CHANNELS];

void setup() {
  Serial.begin(115200);
  while (!Serial)
  pinMode(LED_BUILTIN, OUTPUT);


  //inicia y permite la comunicacion con el sensor
  if (!ams.begin()) {
    Serial.println("could not connect to sensor! Please check your wiring.");
    while (1)
      ;
  }
}
void loop() {

  //temperature  sensor
  //uint8_t temp = ams.readTemperature();

  //ams.drvOn(); // descomentar esto si quieres usar el led del sensor para hacer medidas
  ams.startMeasurement();  //begin a measurement

  //permite que el sensor lea la data cuando este disponible
  bool rdy = false;
  while (!rdy) {
    delay(5);
    rdy = ams.dataReady();
  }
  //ams.drvOff(); //descomentar esto si quieres usar el led del sensor para hacer medidas

  //lee los valores!
  ams.readRawValues(sensorValues);
  //ams.readCalibratedValues(calibratedValues);

  //Serial.print("{");
  //Serial.print("Temp: ");
  //Serial.print(temp);
  //Serial.print(",");
  //Serial.print(" Violet: ");
  Serial.print(sensorValues[AS726x_VIOLET]);
  Serial.print(",");
  //Serial.print(" Blue: ");
  Serial.print(sensorValues[AS726x_BLUE]);
  Serial.print(",");
  //Serial.print(" Green: ");
  Serial.print(sensorValues[AS726x_GREEN]);
  Serial.print(",");
  //Serial.print(" Yellow: ");
  Serial.print(sensorValues[AS726x_YELLOW]);
  Serial.print(",");
  //Serial.print(" Orange: ");
  Serial.print(sensorValues[AS726x_ORANGE]);
  Serial.print(",");
  //Serial.print(" Red: ");
  Serial.print(sensorValues[AS726x_RED]);
  //Serial.print("}");

  Serial.println();
  ;
}

I have set up Baud speed to very high, but this makes no difference. Here is the Mathematica Notebook

dev = DeviceOpen["Serial", {"COM3", "BaudRate" -> 115200}]

parseData[{val1__, 44, val2__, 44, val3__, 44, val4__, 44, val5__, 44,
    val6__}] := 
 ToExpression@
    FromCharacterCode@# & /@ {{val1}, {val2}, {val3}, {val4}, {val5}, \
{val6}}
parseData[___] := Sequence[]

rawReadings = {}

Dynamic[ListLinePlot[Transpose[parseData /@ rawReadings], 
  PlotLegends -> Automatic]]

DeviceClose[dev]

My first thought is to change the USB cable with one you have tested to have good data transfer speeds.

You should send raw bytes using Serial.write and then import them using something like ImportByteArray[ByteArray[yourData], "UnsignedInteger16"] (if for ADC values). Then you bypass encoding/decoding stage, and can pack 1 byte of real data per Serial.write
