I had a similar issue.

I have 2 x IMAP account connections totalling 100+ folders and my entire email archive is around 5GB.

Just over 2 weeks ago TB3 started to use huge amount of RAM and CPU power. At its worst, it was up to 1.5GB of RAM after just a few minutes of being started.

I disabled global indexing and searching, restarted and ever since I've had no issues. Average memory usage is now between 60-80MB of RAM.
