I've had a problem for some days with mailboxes operations like
sam, dam etc.<br>
Those operations are too slow, I have some mailboxes with many
subfolders when I applied a sam command to allow other user access
it, the command spends too much time (e.g 20hours).<br>
There's nothing weird in logs or etc.<br>

I/O contention on the device where your mailboxes.db is stored ?<br>
<br>
<br>
This file can grow pretty large (with many 'holes' in it).<br>
Here, after every user mass delete (once or twice a year) I
'compact'<br>
it by dumping to text and 'undumping' back into skiplist.<br>
Oh, and it's stored on Solid State.<br>
