pi-tool very high resource utilisation when running

[shortbloke]

Given the pi-tool is meant to show you the current load on the Pi. Having it constantly use > 100% CPU for pi-tool and > 50% CPU for 2nd instance of the process, along with ~2.3% for the daemon dramatically increases the load on the system, and increases its temperature. Due to the constant load the CPU keeps the clock speed at ~1.5GHz.

Application is either terribly inefficient or querying and updating too frequently.

I noticed I get power warnings as soon as I open the monitoring app (no overlocking set). I know the warnings are due to a cheap 5V/3A power supply, as official documentation nowadays recommends 5.1V/3.0A supplies. Still a monitoring app shouldn't nearly add as much to the power draw as say a media centre application or so. The Pi-Tool seems simply way too bulky for a tool that plots a few graphs, listens to a button and may occasionally alter some system config files. Having to use overclocking in order to be able to overclock defeats the purpose.
