I experiencing equivalent problems.
I run Thunderbird 38.3.0 on Fedora 22.

When Thunderbird runs longer than a day (and my Laptop is going into suspend für several hours in between, if that has any influence), it becomes very laggy too.

I followed several suggestions on this page and some helped a bit. But the problem itself persists. The problem is getting worse, if you have some calendars, that are not accessible (due to DNS, VPN, WiFi or similar).

The only chance to speed it up again is to quit and restart Thunderbird.

If I restart Thunderbird, the file "<profile>/calendar-data/cache.sqlite-wal" will be removed and
is recreated upon restart. After this, I can use Thunderbird for some hours without problems.

I think the developers should investigate the behavior of Lightning, if it has problems to connect to
the CalDav servers...
