Thunderbird is not very responsive when opening windows, or typing, why? ...or can I fix this?
I have moved over from Outlook to Thunderbird. There are many things to like about Thunderbird (with Lightning). However, I am finding that the program is not very responsive. I often have to wait several seconds for typing to appear, for windows to respond to mouse clicks etc. After the initial wait from a click or typing, I can usually get good response time to my inputs, but if I change to another part of the program it slows again. I have an 8 core AMD 8370 CPU (hardly a slouch) and 16 GB RAM. This should not be happening. I do have some extensions (Lightning, Forecastfox, ImportExportTools, and Menu Wizard) installed, but when I disable them (except Lightning; absolutely need that) I do not notice an improvement.
Is this still being worked on? Or is there something that I can do to reduce this response lag?

What is your anti-virus software?
Webroot.
Initial disable of webroot did indeed improve things. But restart of webroot did not make things worse again.
I looked to see if webroot installed a plugin or extension, but I don't see that it has done that. Most of the settings in webroot that are not part of virus scanning and detection concern itself with firefox (and other browsers), not thunderbird. In fact I could not find any setting I could change that affected thunderbird (of course that does not mean it isn't doing something in that realm).
I have also noticed that sometimes a system reboot helps as well--but not always. I don't like having to do that though.
I know this isn't very helpful, but I guess that is why I am asking.
Look for an option to create an exception. The real-time scanner should not scan the Thunderbird profile folder. For more information on the profile location see http://kb.mozillazine.org/Profile_folder_-_Thunderbird
