Hello

I wonder if anyone here has a solution to my issue.

System:
Windows 10 - up to date
Thunderbird 60.9.0 (32-bit) - not updating as I had issues with GContactSync when I did, so had to reinstall Thunderbird.

Addons:
GcontactSync
Lightning
Provider for Google calendar

Now my problem is Thunderbird is sluggish.
It will freeze up for 5 seconds and not respond, then carry on as normal, then may freeze up again and so on.
It happens browsing emails or starting a new mail.
For example, when I start a new mail, I start typing the email address and nothing happens. Then suddenly it will fill in the address and I can carry on.
It's not every time though.

Another example. I click on a mail to read it. Freeze... then display. But again not every time.

I tried starting Thunderbird in safe mode (i.e. no extensions), made no difference.

Is there a log I canget hold of to post here for you to have a look at?

How is the account (or accounts) set up in Thunderbird, as POP or IMAP? Find out using menu path Tools->Account Settings->Server Settings->Server Type at the top right of the dialogue.

Mail accounts are all IMAP - they were always IMAP.

I forgot to mention that the same Thunderbird version on a Windows XP machine with the same accounts runs fine - no sluggish performance.

What security software are you running on that system?

I made an exception in Windows Defender to not scan Thunderbird and that helped a bit.

Sorry, I can't give detailed instructions. I had to go through hoops to find where to do that, and I use primarily use Linux.
Linux Desktop - AMD Athlon(tm) II X3 455 3.3GHz | 8.0GB RAM | GeForce GT 630
Windows Notebook - AMD A8 7410 2.2GHz | 6.0GB RAM | AMD Radeon R5
