Does anyone know why my Apple mail inboxes are taking an extremely long time to load? In other words, sometimes it takes up to 4 minutes for unread messages in a folder to display when I click on that folder. Is this an indexing issue, or something else?

Not sure if this is relevant to situation, but Spotlight begins reindexing my entire drive every single time I reboot. The entire drive - for hours, and this is slowing everything down. I have tried turning spotlight on and off - nothing works...

Figured this one out. It is Mavericks slowing it down.

It might be spotlight-related, as you mentioned. Assuming your mail accounts are IMAP, then one thing to try is to quit Mail. In your ~/Library/Mail/ folder, there is a file "Envelope Index". Move that file to a safe place (like, your Desktop), and restart mail. You will probably see a "welcome" screen, and then Mail will go through your messages. After the main Mail window finally appears, it might be slow for a while, as Spotlight will again re-index the messages; but, not as slow as before.

In general, I've found that this is a fairly reliable way to fix the problem you're having; and, have done it for several accounts at work. The "Envelope Index" file will be recreated; but, it should be a "cleaner" version.

Thanks Kent. But if Spotlight is indexing the entire computer hard drive, is there a way to simply make Spotlight stop re-indexing constantly? – Ben Greenfield Sep 17 '13 at 1:39
Apple's way: And, another way which does the same thing:… But, even then, the mail folder might be handled differently... – Kent Sep 17 '13 at 1:56
