Terrible performance with folders with 5000+ files?

I have a mail folder with *well* over that number of messages (multiple folders with over 30K messages), and don't have this particular issue there... I smart update it daily. I think there's likely something else going on with your particular situation, which is why I suggested it might be something in the OS in your folder.

We are not tracking the files with any ID. We're not looking them up, or doing anything with a database. There's no reason a large number of files in a given folder would be slower than a small number, unless there's a system issue involved...
