Please could you help me to understand and fix why my dovecot IMAP
</div>
<div>
performance is so bad? I've read through a lot of the
</div>
<div>
performance-related material on the website, but I don't think that any
</div>
<div>
of it could account for slowness at the level that I am seeing.

The simplest scenario is moving a message from my Inbox to another IMAP
</div>
<div>
folder. Using Gnus as the client, the whole UI freezes for about 2
</div>
<div>
minutes (which I assume is until the move is complete), and journalctl

<div>
on the dovecot server says:

or the same message with (rotating while syncing).

There must be something badly wrong in my setup, or perhaps in the spec
</div>
<div>
of the server that dovecot is running on. What should I look at to
</div>
<div>
start understanding this better?

Many thanks - Neil
