dovecot - Mar 2008 - Sorting a folder (by THREAD) takes a long time

My email workflow with Dovecot is that mail gets delivered to INBOX, 
where I handle it and then move it into a folder called archive.

I have alpine set to use the Default sort of "THREAD" of a folder. 
After
moving a (few) mail(s) from INBOX to archive, archive takes a long time 
(10-50s) to load while alpine tells me:

                          [Sorting "archive"  ... ]

(I can do the IMAP traces, but I figure alpine's terminology is going to 
be so similar to IMAP terminology that it should be straightforward enough 
for Timo to know what I'm talking about.)

I don't actually know enough about Dovecot to say for sure what makes this 
slow, but maybe it's just indexes not being updated?  What might be making 
this slow, and what hope is there for it being fast? (-:

It seems like the really nice thing to do would be, after the save, in the 
background examine the archive folder and update whatever caches need to 
be updated.  The more work that happens while I'm not waiting, the happier 
I'll be!  (Same goes for my mom, and the other less-technical users of 
Dovecot.)

Is this the kind of thing I could write a plugin for...?

How large is your INBOX? Unless you've disabled index files the  
threading should go pretty fast even for thousands of messages.

But if it really is because of THREAD, you're in luck. I've almost  
finished thread index implementation and I'm also considering making  
it available for v1.1 as a plugin.

I'd do the traces if I were you. Maybe it's something to do with
"Thread
Sorts By Arrival" or similar Alpine threading quirks. There was also 
traffic a couple months ago about threading scaling non-linearly in Alpine 
depending on that setting. I assume you're running a recent snapshot, but 
I don't recall whether that issue was resolved.

Hi,

I'm using delivery like Postifx->Amavis->Dovecot LDA
Is there a possibility to deliver mail marked as spam (Subject, header) to
Junk folder?

Curious... did you mean 1.0? I'm trying to figure out what else you 
would be developing for...
