Reproducible: Always Steps to Reproduce: 1. Open a window in a standalone window. 2. Delete the message. 3. It takes about 2-5 seconds for the window to close. It does not take this long to delete messages when using version 3.1. Also, I think it might only be HTML messages that take this long. Plain text messages appear to delete and the window closes much quicker.
Can you reproduce this issue in safe-mode? ( see how-to start TB in safe-mode here http://support.mozillamessaging.com/bg/kb/Safe+Mode ) Do you have antivirus enabled? Can you try with antivirus disabled?
That support document does not pertain to Firefox 4 or Thunderbird 3.3 which changed the way to load in Safe Mode. Running in safe mode made no difference to the speed. But, turning off my anti-virus did make a difference. I guess I need to see if there is a way for me to tweak the anti-virus.
I am running Microsoft Security Essentials for my anti-virus. I have removed the following directories from scanning and it does appear to be faster, but still not as fast as version 3.1. Also, I do not like not having these directories scanned. c:\program files (x86)\miramar c:\users\jeff\appdata\local\thunderbird\profiles c:\users\jeff\appdata\roaming\thunderbird
I am not aware of any performance regressions between TB3.1 and 3.3. So I suspect this is something unique to your environment. I don't think you should be excluding (x86)\miramar - that's not a profile directory Do you have other spyware or firewall software? see also bug 621083 comment 8 http://kb.mozillazine.org/Standard_diagnostic_-_Thunderbird https://wiki.mozilla.org/Thunderbird:Testing:Memory_Usage_Problems
