Unexpected CPU load

[mjm987]

ExchangeCalendar is configured to sync every 300s so I would expect nearly no raise of CPU load.

But when enabling ExchangeCalendar (rel. 3.9) the CPU load of thunderbird raises fom 0.3% to 2.3% and powertop from 30 events/s to 130 events/s which drains battery on notebooks.

Thx Matthias

Hi, please try with the latest beta of version 4 and reopen in case the problem still occurs.

With v4.0.0-beta4 it's even worse: 8% CPU load and >300 events/s on powertop

Thunderbird is release 52.2.1 (64-bit, Linux)

I faced the same problem. Without Exchange Calendar, the CPU is around 0.3 --> 0.7, with Exchange Calendar, CPU uses constantly around 2.5 - 3%. I really like this extension, but this constantly 3% CPU usage is unacceptable. I tried with both v4 and v5.alpha2, Thunderbird 60, Ubuntu 18.04
