I experience performance problems: Every time a connection is made to the SMTP server, TBird freezes for couple of seconds. How to debug this?

I did close 25 messages rules. Disabled "Nostalgia" add-on. How can I investigate what is causing this ? I did set in account > Server details to check for new messages every 3 hour. However it seems that every time I send an e-mail again a smtp server roundtrip is made, thunderbird freezes while writing my next message.

running TB in safe mode now. The experience is slightly better. However every time I move some mails from inbox to an archive folder, there is this "not responding" issue.

You're supposed to start Windows in safe mode as per the instructions.

Worse, I even started using Outlook. (After 15years, worth a try, but not what i am looking for.)
