I'm running a Core Duo MacBook Pro, 2GB RAM, OS X 10.5.5.

Recently (and I'm not sure if this followed an update or not), I've been having serious lack-of-speed issues with Mail. When I open a message, the window pops up immediately, followed quickly (sometimes a slight delay but usually not a perceptible one) by the headers. It then takes about 40-45 seconds (counting to 40-one-thousand, haven't used a stopwatch) for the message body to come up.

This happens with emails from both POP and IMAP accounts, in both my inbox as well as "normal" folders on my Mac. I do have a decent number of accounts (some POP, some IMAP) and a whole lot of mail saved on my Mac, but that's been true since before I started having this problem.

I've tried rebuilding a mailbox, and it didn't ameliorate the problem.

Any other thoughts appreciated.

MacBook Pro, Mac OS X (10.5.5)

    Oh, one other bit of info: Mail is unresponsive while loading the message body (i.e. attempting to pull up another message or switch to another Mail window results in a spinning pinwheel; switching to another application works fine).

    Further info:

    Mail is slamming the CPU, apparently in a single-threaded manner, while this is going on (I'm seeing 60-80% currently while also having iSquint/ffmpeg running, and the latter goes back up to 120-130% when Mail finishes opening a message body).

    I have a similar machine and OS. I have the same problem. Not the server because my dual Intel opens things fine. I hear the disk flailing.

    Also, (try this) if I select a message and pick "reply" it renders immediately, so there is something going on when you click it to open that makes it slow. I think that it may be a bug or slowness in rendering HTML or something, because REPLY often just turns things into plain text, and then it is very fast.

    See if the reply thing gets you instant look at message. It's weird, because I very often have to reply to a message in order to read it! THen I just close down the reply window.

    I have a similar problem - when I open up my Mail window, nothing appears in the message windows, and the little loading circle (pie with a slice out of it, perhaps?) appears for a good minute before I can see any messages. I can compose new messages and send them, it just takes forever for the existing messages to appear. It's a huge pain - I can check my email through the Internet before Mail even finishes loading. Any ideas? I don't think it's because the messages are too big because I've accidentally gone over my quota before, and I never had a problem like this.

    I have been having a similar problem with slow to load mail on my iMac. It usually happens when I have multiple emails yet to be read... the first few come up normally, but then the "Loading..." message appears and I'm in for a wait. When I load webmail this never happens, only with the Apple Mail app.

    Any ideas?

    similar problem since updating to 10.5.

    Mail opens fine, downloads fine. Some messages open okay, but more often opening a message takes minutes, with the spinning ball of ****. Sometimes it can take me near an hour to check my mail.

    I've rebuilt all the mailboxes. Also archived and deleted most of the saved mails, in case overfilled folders were causing grief.

    I recently bought this upgrade so I may still be in the complimentary time and have a case filed, but I didn't get much help earlier on with other issues. I'm really not thrilled with this version, probably the worst I can remember since Apple II.

    I may go to Mozilla or such to solve this mail problem.

    Macbook Core 2 Duo 2GHz, OS 10.4.11:

    I have a similar issue, but only when opening a message that is digitally signed (usually one I've sent to myself from work). Unsigned messages open immediately. Signed messages start to open, then I get "Loading Message" for up to a minute or more. While this is happening, the machine is unresponsive not only in Mail but in other applications as well. These are plain-text messages, not large. If I go back and open the message later, it's much faster the second time.

    The odd thing to me is that my wife does not have this problem with her computer, which is exactly the same as mine except for some installed software. For example, I have the new version of Microsoft Office and she doesn't. Hmmm......

    I also see this problem. Mail often takes more than 30 seconds to open a mail message, no matter how simple. Even a four line text-only mail message can take 30 seconds or more to open. On occasion, Mail takes several minutes to open a message -- enough time to boot Windows!

    I've been having many problems since upgrading to 10.5, the mail issue was just the tip of an iceberg. I thought possibly my problems were because I'm on a G4 Powerbook, not intel.

    In any case I tried to reformat with 10.5 and the nightmare grew beyond proportion.

    I've gone back to 10.4.11 and everything is happy again.

    There's some bad about that system (10.5). I wish I could get my money back.

    I am a heavy email user - 100 to 200 emails a day sometimes. My Apple Mail was so slow that I got in the habit of clicking on an email and then going to another application to keep working and check back from time to time to see the email opened. I'd then read it, click on another and repeat the process. a serious drag on productivity. I came across this tip on another site and it worked very well for me. Not sure how long it will last.

    Here is the link:

    Here is the meat of the post:

    +You can check your current 'envelope archive' size by entering this in the terminal:+
    +ls -lah ~/Library/Mail/Envelope\ Index+

    +Then to optimise it (cleans out stuff that has been marked for deletion but not actually deleted, defragments the structure, etc):+
    +sqlite3 ~/Library/Mail/Envelope\ Index vacuum;+

    +Then check your envelope archive size again to see the results…+
    +ls -lah ~/Library/Mail/Envelope\ Index+

    +It compacted my envelope archive down from 55MB to 50MB — not a huge increase, but the speed difference was dramatic.+
