Multiple QNetworkRequest slows the GUI performance

//Now can you help me with a solution which wont effect my performance.

I gave you one. Read my post again. You cannot poll every LED every second if it takes more than one second for the LED to respond. You have to treat every LED (or group of LEDs) independently:

- Ask the LED group for its data
- Wait for the finished() signal
- Get the data and tell the plot to update
- Wait one second (for that LED group only)
- Repeat

What is the point of setting a performance goal (one second updates of everything) when your hardware cannot perform at that rate? Asking for data more often won't make it come in any faster.
