MQTT too slow about pix

[moelha]

After a series of tests on Node-RED, it was ruled out that MQTT was the actual bottleneck. An inject node was used to generate timestamps and print them on the dashboard, where the sensor data is.

There are consistent delays with fast data (aka a data point every 0.01 seconds). Node-RED is therefore too slow processing and rendering the data on the dashboard in real time.

At this point, the most important thing is data-logging, streaming is secondary. In the near future, other means of faster data-displaying will be evaluated.
