This is a great Add-On. However, I am having the slow-down issue with it. Fairly frequently, my CPU usage will go up to +50% for 2 or 3 minutes, making Thunderbird completely unuseable. As I use email/calendar many times a day, I am finding this very hard to deal with.

I am wondering if this issue is not so much an issue with Provider per-se, but with Lightning itself... This bug seems possibly related: https://bugzilla.mozilla.org/show_bug.cgi?id=462283
As this bug shows the problem being resolved in TB3 with the latest Lightning... I hope that will fix this or I won't be able to use, which would be a shame.
