Network: TCP speed is too slow

I want to read data from a Wifi module using TCP and plot in Processing. Right now I am just sending a loop of counter values (from 0 to 1000) from the other end. The code in my Processing takes around 16660 milliseconds to read 1000 values. I checked in the Hyperterminal, which reads the data lot faster. Why is it so slow?
I tried to check which part is causing the delay but couldn't figure out.
Here is my code:
import processing.net.*;

Client myClient;

int count = 0;

byte[] inBuffer = new byte[10];

int nl = 10;

void setup() {

size (400, 300);

background(0);

myClient = new Client(this, "169.254.1.1", 2000);

int m = millis();

}

void draw()

{

if (myClient.available() > 0)

{

myClient.readBytesUntil(nl, inBuffer);

String s = new String(inBuffer);

println( s);

count++;

if (count ==1000)

{

println("Time = " + (millis() - m));

delay(1000);

m= millis();

count = 0;

}

}

}

Plotting multiple realtime signals

I need a realtime plotting of 3 signals (like we do using subplot() in MATLAB). How can I do that is Processing?
