Just browsing, I noticed that my ventilator was heavily working. "top" revealed that it was Thunderbird that was spiking the cpu, even though it had just been open in the background for a long time. My computer was up for 3 hours 15 minutes at that time. Indeed, the output of top below, sorted by TIME+, indeed demonstrates that thunderbird needed s=tremendous more processor time than other applications
