Please run the performance profiler:

1. install profiler add-on into thunderbird - download the file from https://github.com/firefox-devtools/Gecko-Profiler-Addon/blob/master/gecko_profiler.xpi?raw=true and in Tools > add-ons click the gear to install add-on from file

2. Follow instructions at https://profiler.firefox.com/   (videos BASED ON FIREFOX at https://profiler.firefox.com/docs/#/./videos-intro )

You must be using Thunderbird 67.0b3 from https://www.thunderbird.net/en-US/channel/ or current nightly build from https://archive.mozilla.org/pub/thunderbird/nightly/latest-comm-central/

And backup your profile before testing - https://support.mozilla.org/en-US/kb/profiles-where-thunderbird-stores-user-data#w_backing-up-a-profile
