Deleting messages in Thunderbird suddenly slow SOLVED: caused by Time Warner Cable
Just during the last month or three Thunderbird has become extremely slow in deleting messages. It's not my antivirus. I'm using Windows Defender, always have and nothing has changed there. I'm using Windows 8.1. Thunderbird worked fine until recently, then all of a sudden it's started taking 10 seconds or so to delete each message. Multiply that by 20 or 30 messages a day, and that's a real time waster.
There seems to be a logic bottleneck somewhere. Files should work quickly regardless of size. Whether random or sequential filing, 100 records or 100,000 records, should be just as fast. Tells me the logic is messed up somewhere. I am a professional programmer with some 35 years experience. None of my other programs have slowed down. No other part of Thunderbird has slowed down-- only deleting messages. I've tried cleaning trash, compressing files, etc.
Educated opinion: logic bug.

Before taking the drastic step of creating a new profile, an easier step is safe mode (which is also a proper first step in Firefox):
Start *Windows'* safe mode with networking enabled - win8 https://support.microsoft.com/en-us/help/17076/windows-8-startup-settings-safe-mode Still In Windows safe mode, start thunderbird in safe mode - https://support.mozilla.org/kb/safe-mode-thunderbird

Try creating a new Thunderbird Profile to see if it does the same.
Profile folder - Thunderbird Profile Manager
If that works, then: Create a clean new profile in Thunderbird and import your stuff from the old profile

This actually seems to be a problem with Time Warner Cable. I discovered this when I found that my Thunderbird email deletions work a lot faster when it's late at night (and most people are off the Internet). Slows down terribly around 6pm.
Looks like it's time to contact the FCC about TW throttling / overselling cable lines again.
Thanks for the update
