Increase update frequency when few items are requested

[PawelPyta]

Hey, I'm using your app for my thesis project and it's great. I'm currently looking to read 4-5 OBD data items and send them over MQTT with a frequency of about 5 Hz. I already modified the MQTT plugin code to speed it up, but the main app is sending updates about every 2.3 s. Can this be sped up? I already deselected every unused OBD item, because I assume the fewer values are polled, the faster the response from the adapter. When plotting a single value in the main app, it is a LOT faster, almost real-time. That means the potential is there, but I am not skilled enough to understand and modify the main app code.

If you can not increase update speed with above hints, pls provide log file for analysis ...
