BiglyBT: Turn off the heating and save energy.

[lgillis]

The BitTorrent client BiglyBT (BBt) permanently produces temperatures at least 10°C higher than necessary. Measured here, it depends on the hardware. The result is that the hardware wears out faster due to higher temperatures, the batteries discharge faster and the costs increase. The following shell script limits the CPU usage by BBt to a tolerable 20 percent. Data transmission doesn't suffer, it's the built-in bells and whistles that we all love so much that are throttled a bit with this. Simply call it after BBt has been started and forget it, it terminates itself when BBt is terminated.
