Thunderbird sending POP email is very slow. Tried reinstalling Thunderbird, disabling anti-virus software, using Thunderfix, disabling plug-ins and compacting file memory.
Sending an e-mail now takes over a minute with a fast Centurylink upload connection in excess of 13Mbs. This is a problem with multiple computers.
I have tried everything I can think of at my end per above troubleshooting steps.
How can I further determine if it is a Thunderbird problem or a centurylink mail-server issue?
I would appreciate any insight you might be able to provide.

I copied the files you recommended as well as other recently modified data files from the old profile to the new one. That effectively restored my settings to the new problem-free profile.
Thank you for all of your help.

I see you have a Bitdefender toolbar. If BD is the main antivirus, add the TB profile folder as an exclusion. The profile folder location is shown in Help/More Troubleshooting, about:profiles. You might also want to disable the 'Advanced Threat Defense' option. The best way to test if BD or any startup app is affecting TB performance is to run Windows in safe mode.
I added the TB exception which failed to help. I then turned off Bitdefender and Malwarebytes and there was no change.
I will check on safe mode later to see if something else might be conflicting.
Thanks for your prompt assistance.
The problem persists in safe mode.
Since there don't appear to be any obvious factors causing the issue, I suggest you go through this list to see if any apply to your setup: https://wiki.mozilla.org/Thunderbird:Testing:Memory_Usage_Problems
I checked all of the "Testing:Memory /Usage Problems" but none of those helped.
What next?
I would try a new profile with a single account. Test the new profile, and if works properly, data can be transferred from the old profile to the new. Create and manage profiles from Help/More Troubleshooting, about:profiles, or launch Profile Manager from a Run window (Winkey+R) by typing thunderbird.exe -p
That worked!
How do I transfer the information from the old profile to the new one?
Copy the local mail from the old profile to the new by copying mbox files from Mail/<popservername>, Mail/Local Folders, and sbd subdirectories, to Mail/Local Folders of the new profile. The mbox files are the large files with no extension, named after folders, e.g. Inbox. Copy abook.sqlite (Personal Address Book) and history.sqlite (Collected Addresses) from the old to the new. There are other files that can be transferred if necessary.
