Steps to reproduce:

Make sure autosave is turned on
Start composing a new message.
Attach some big file (such as a few megabytes)
keep typing the new message

Actual results:

Every once in a while, when the message is automatically saved, thunderbird completely blocksb and stops responding until saving is done. This can take several seconds

Expected results:

Oh, do I need to say it? Saving should be done asynchronously and shouldn't block the interface.

(In reply to matteo sisti sette from comment #0)
I think you need to enable SMTP logging After that, we can see where the issue is.

There was a similar bug (bug 716791). Do you have anti-virus installed?

No antivirus, no (do they even exist in Linux?)
Most probably this is a dupe of bug #319058: matteo do you agree?

They are two different issues. Saving should be done asynchronously in a separate thread  regardless of whether or not attachment are attached when autosaving.
The issue in this report is not that saving takes too long, it's that it blocks Thunderbird during the whole time it takes.

Obviously not attaching the attachments would make this bug much less relevant, but indeed I don't even agree that the attachments should not be included when autosaving. They should be included _and_ re-attached from source prior to sending if still available.

I can reproduce this.  And I would expect beach ball on Mac.  The larger the file, and I assume the slower the server, the larger the delay.  I tested with a mere 46MB file.

bug 319058 should be investigated IMO, though perhaps not even possible to do, given how we  handle attachments (I think starting in v3?)

anyway, I don't find any obvious duplicates. confirming
