title: Wake + Wifi lock no effect
body: <p>My background service is sending messages to a local server as fast as possible.
  Each message takes normally about 30ms. But when the phone is in sleep mode it takes around 400ms-1000ms (screen off with the 'correct' Wifi-policy)</p>
  
  <p>Within my service I'm using the following code to acquire a Wifi-lock and WakeLock.</p>
  
  <pre><code>PowerManager lPowerManager = (PowerManager) getSystemService(Context.POWER_SERVICE);            
  mWakeLock = lPowerManager.newWakeLock(PowerManager.PARTIAL_WAKE_LOCK, "WakeLockTag");
  
  WifiManager lWifiManager = (WifiManager) getSystemService(Context.WIFI_SERVICE);
  if (Build.VERSION.SDK_INT &gt;= Build.VERSION_CODES.HONEYCOMB_MR1) {
      mWifiLock = lWifiManager.createWifiLock(WifiManager.WIFI_MODE_FULL_HIGH_PERF, "LockTag");
  } else {
      mWifiLock = lWifiManager.createWifiLock(WifiManager.WIFI_MODE_FULL, "LockTag");             
  }
  mWifiLock.acquire();
  mWakeLock.acquire();
  </code></pre>
  
  <p>Is it possible to get the same performance as when the screen is on?</p>
