For a fair comparison, Grafana should have been with combined with InfluxDB, which is sort of the default configuration. I've been using Grafana / InfluxDB for a personal domotica project. Given that I run it on cheap virtualised hardware, it's blazingly fast, extremely easy to use (for devs), intuitive and many client libraries for InfluxDB exist (Scala, Java, Python, R, to name a few). Couple of restrictions: - It's best for the relationship: "time", "tag", "scalar". Multi-scalar rendering is possible using a plugin, but it's not designed for it. - Density plots are not supported yet. Limited support for heatmaps. - Due to JSON serialisation, server-side compression is definitely necessary. With zopfli, I've seen compression to below 3%. This, however, entails a (limited) CPU load. - Retention and aggregation in influxdb are possible, but it's best to design this upfront.
