Mail program is CONSTANTLY writing changes to disk, and it bogs EVERYTHING down...

Same thing here. Mail eventually quits retrieving from gmail as well and I have to restart it to get it pull new mail. That usually triggers a repull of hundreds of messages and old partially typed drafts show up again as well. This, along with the distnoted memory leak have me wishing I could roll back to Lion.

How did you "re-index" the messages?

Thanks.

Mavricks Mail is Writing Changes to Disk for gmail every reboot, still!

There was an update that was supposed to fix this. It hasn't. Is there some resinstall/delete prefs/stop-start I can do to get this to stop?

This needs to be fixed. I'm leaving for overseas trip and can't be sucking up bandwidth re-downloading 30,000 messages every day. Maybe I should have gmail forward to icloud, then just read icloud? WTH?

Has anyone found a fix for this yet. My Mac has slowed down to a crawl.

You might want to consider starting a new discussion. Since this one is marked solved, less people are likely to look at it.

You can link this discussion in the post.

Sorry Eric if you read the post 2 before mine it did not fix it.

That last update from apple 2 days ago fixed it for a day and now it is so bad I can't check and read my mail with out becoming unhinged.

I find it worse now.

Easiest fix I found was to switch to Thunderbird - which was problematic under Lion but whooshes along under Mavericks. Mail would sit there for hours transferring mail and eating memory until Mavericks paused it and invited me to kill it. Thunderbird completed all mailbox updates on two accounts in minutes.

TRY THIS FIX - worked for me 100%

Check you setting on gmail (the website). Go to Settings, then Labels.

Make sur there are no "/" in the path of your mailboxes (first column).

Then I recommend you also do a sync (control-click your main inbox in Mail).

That's it, as silly as it sounds.

Good luck
