[HELP] Regular Udp-Code to AsyncUDP

[luxorbis]

This may be a rather trivial question, but I don't know/understand what i have to change in my currently working code to get it to work with this library. The reason I'm considering this is because the current version is too slow(~23 packets per second). The data I'm receiving is from a game in form of structs, so the issue can't be there. After receiving I plan on sending the data over to another µC.

//#include <ESPAsyncUDP.h>

#include <ESP8266WiFi.h>   //connection to wifi
#include <WiFiUdp.h>       //UDP data transfer
#pragma pack(1)            //enable structure packing

#ifndef STASSI
#define STASSID "***********"
#define STAPSK  "*********"
#endif

char packetBuffer[UDP_TX_PACKET_MAX_SIZE]; //buffer to hold incoming packet,
const unsigned int localPort = 8687;

WiFiUDP Udp;
//=======Data Structure to Send======================

  char gear;
  word speedkmh;

struct PacketHeader{

  uint8     m_packetId;             // Identifier for the packet type, see below
  uint64    m_sessionUID;           // Unique identifier for the session
  float     m_sessionTime;          // Session timestamp
  uint      m_frameIdentifier;      // Identifier for the frame the data was retrieved on
  uint8     m_playerCarIndex;       // Index of player's car in the array
};

  Serial.print("Connected! IP address: ");
  Serial.println(WiFi.localIP());
  Serial.printf("UDP server on port %d\n", localPort);

void loop() {
int packetSize = Udp.parsePacket(); //Doesn't always trigger, around 40ms recovery Time
  if (packetSize) {   
      udpReceive(packetSize);

    int n = Udp.read(packetBuffer, packetSize);     // read the packet into packetBuffer
    byte packetId = (byte) ((PacketHeader*) &packetBuffer)->m_packetId;
    if (packetId == 6) {                        //rate specified in game
        byte playerIndex = (byte) ((PacketHeader*) &packetBuffer)->m_playerCarIndex;
        fastData.gear = (char) (((PacketCarTelemetryData*) &packetBuffer)->m_carTelemetryData[playerIndex]).m_gear;

      }   
}

Your help is much appreciated!!

Little Update: Now I can receive data from the app called "Packet Sender", but somehow the udp.onPacket()function doesn't trigger when I enable UDP ingame. UPDATE: everything works so far, I can retrieve data, but somehow the "packet per second"-rate did not improve over the regular WiFiUdp.h library(still around 23 Pps). Maybe this is due to the game bursting out all the packets at a time, or because of the packet-length (largest packet: 1341bytes).
