Thunderbird

I don't know if it's Windows, the implementation of Thunderbird on windows, or just Thunderbird it self, but my inbox is slower than I've ever seen it before!? In Apple's Mail.app it's faster to search for an email than trying to sort them into forlders, which is why i have about 550 emails in my inbox. Why should I move them? Even when working with Thunderbird on Linux the performance was reasonable, and I didn't see a need to clean out my inbox, but with Thunderbird on Windows, it seems like my first task of the day to clean out my inbox. It can't even handle junk mail without taking forever to finish. If I mark something as junk, my junk settings require it to move my junk mails to the junk folder. That just doesn't happen. To try and force it, I manually run the "Run junkmail controls on folder" tool, but that just seems to want to download all email again and go through each and every one of them. It's strange that it doesn't remember having looked through all my email before, and that it just need to look at my new mail. So far I'm staying on Windows, due to my new tasks as a project manager, but I might change to Linux once we figure out which tools and processes we want to use. This means that I probably need to clean out my inbox in order for Thunderbird to function sufficiently - at least thats my guess - but apparently thats a very good idea to do generally. I've been reading "Getting Things Done" by David Allen, and one of the things he's talking about, is reducing the clutter, so that one can see the relevant tasks. Apparently, the inbox needs to be emptied in order for this to work, so I guess I better get cracking if I want to implement his system at some point :)
