100.5% CPU usage, message creation is tedious

Fwiw, while I was typing this - not using mailmate at all, I watched the Activity Monitor, and mailmate was consistently at or near 100% CPU. There were no spinning gears on the inbox pane and I had one open compose window.

Then I switched back to compose, and now Mailmate is consistently < 2%. AFAIK, I didn't do anything except switch away and back...

This is Mavericks on an 11" Macbook Air.

The number of messages is quite low and shouldn't be the problem. First try updating to the latest beta (if you haven't already). See the Software Update preferences pane.

If you still have this problem then use Activity Monitor to make a process sample during one of these delays (it doesn't have to be all the time, just make sure the sample covers one of these delays).

Thanks in advance.

Thanks. I've downloaded and installed (I was on 3905, now 4025). It was high after re-opening, but ok now. I'll keep an eye on it and grab a sample if it comes back. Thanks again!

Another clue. My firewall says I've downloaded 13GB of mail in the past 7 days (including this morning when it was slow). Fastmail says I have 2.2GB total. Perhaps it's confused...?

Ouch 54GB this month...

I don't really know how to correctly interpret the firewall numbers, but it does sound like an awful lot.

You can keep the “Activity Viewer” (⌥⌘0) open if you want to see if MailMate is somehow busy-looping some command to
the server. If it is the it's not a known issue.

Do you still have the issue with the beta? Did you manage to make a process sample? (Let me know if you need more specific instructions to do this.)

Thanks for the feedback.

CPU is definitely improved with the new version, but right now hovering around 50% and the Deleted Messages folder has been spinning for a few minutes and composing a new message seems to lag a bit while that's happening. I've attached the process snapshot.

Fwiw, my Trash (Deleted Messages) folder has 13621 messages for 808MB total.

Hope this helps. Thanks!
