100% cpu and response time amazingly bad.
I am running Thunderbird 52.2.1 on Fedora25. I have 5 accounts with about 200K messages and 10G of storage. I have tried to stop Thunderbird from downloading all the email from the server. I am seeing very bad response times to the point where my desktop is complaining that thunderbird it taking too long to respond and it can take several seconds for any keyboard characters to appear. Also almost all the time thunderbird has a processor core pinned at 100%

Check the Activity Manager. Tools (Alt-T) - Activity Manager
Thunderbird may be busy indexing your downloaded messages if you have Global Search turned on.
Its been several weeks since I re-installed. So that would be a lot of indexing. I am not seeing anything in the activity manager.
Things also seem to get worse over time. I leave my email open 24x7.
Then I'd probably try to restart Thunderbird.
That kind of sucks as a solution.
That is why I dropped using windows in the 90's
