TextFinder really slow?

Hey I am running through the Arduino Cookbook doing examples, this is the code I'm working on atm:

#include <SPI.h>
#include <Ethernet.h>
#include <TextFinder.h>

byte mac[] = { 0xDE, 0xAD, 0xBE, 0xEF, 0xFE, 0xAD }; //physical mac address
byte ip[] = { 131, 181, 87, 145 }; // ip of arduino in lan
byte gateway[] = { 131, 181, 87, 129 }; // internet access via router
byte subnet[] = { 255, 255, 255, 128 }; //subnet mask

EthernetServer server(80); //server port

char buffer[8];

void setup()
{
  Serial.begin(9600);
  Ethernet.begin(mac, ip, gateway, subnet);
  server.begin();
  Serial.println("Ready");
}


void loop()
{
  EthernetClient client = server.available();
  if (client) {
    TextFinder finder(client);
    int type = 0;
    while (client.connected()) {
      if (client.available()) {
        if(finder.getString("","/",buffer,sizeof(buffer))){
          Serial.println(buffer);
          if(strcmp(buffer, "POST ") ==0){
            finder.find("\n\r");
            while(finder.findUntil("pinD", "\n\r")){
              int pin = finder.getValue();
              int val = finder.getValue();
              pinMode(pin, OUTPUT);
              digitalWrite(pin, val);
            }
          }
          sendHeader(client, "POSTing Stuff");
          client.println("<h2>POSTing Stuff</h2>");
          client.print("<form action= '/' method = 'POST'><p><input type = 'hidden' name = 'pinD8' value='0'>");
          client.println("<input type='submit' value='OFF' /></form>");
          client.print("<form action= '/' method = 'POST'><p><input type = 'hidden' name = 'pinD8' value='1'>");
          client.println("<input type='submit' value='ON' /></form>");
          client.println("</body></html>");
          client.stop();
        }
        break;
      }
    }
    }
  }
  
  void sendHeader(EthernetClient client, char *title)
  {
    client.println("HTTP/1.1 200 OK");
    client.println("Content-Type: text/html");
    client.println();
    client.print("<html><head><title>");
    client.print(title);
    client.println("</title><body>");
  }

For some reason it is ridiculously slow. Watching the serial monitor it gets the "POST" on button click from the web page end but takes a full 4-5 seconds to turn the LED on/off, I removed all the delay() the example had but that didn't change anything. Is TextFinder just really slow or something else afoot?

I see no-one is responding. I don't use it, and I would recommend you stick to simpler text processing.

I hate to think what it is doing, but 5 seconds sounds far too long.

You could add debugging prints and try to see what part exactly is slow.
