Hello,
I use IMAP with Gnus. It's very slow, around 30 seconds to get new
mail. I did profiling and the main culprit appears to be imap.el, not
my spam splitting functions. I'm considering moving to another mail
server, but first I'd like to know if something is misconfigured, or
if there's room for improvement in imap.el. Mozilla Mail seems much
faster, for comparison. I'm on a fast network link.
Gnus always pauses right before the "nnimap: Mailbox xyz modified"
message, where xyz is the last mailbox to be "quickly checked" and
the first to be seen as "modified". This is what I mean:
nnimap: Checking mailboxes...
nnimap: Quickly checking mailbox ietf
[ very quick, maybe 1 second ]
nnimap: Quickly checking mailbox INBOX.Drafts
[ pause! ]
nnimap: Mailbox INBOX.Drafts modified
[ slow, maybe 10 - 20 seconds ]
nnimap: Mailbox ietf modified
[ slow, maybe 3 seconds ]
nnimap: Checking mailboxes...done
Here are the ELP results. I instrumented the gnus, nnimap, imap,
nnml, and nnmail packages for a single call of gnus-group-get-news.
Sorry for the verbosity, I wasn't sure what could be important.
Thanks!
Ted

Are all of the quickly changed mailboxes mentioned in the 'Mailbox foo
modified' part? If so, that may be the problem, only mailboxes that
is actually changed should be checked further.
If that is not the case, perhaps the mailbox ietf is very large? Try
archiving it per-month or something.
Finally, the server may simply be inefficient. Some servers search
through the entire mailbox for all SEARCH commands, even commands
which the server should be able to respond to quickly. Try 'strace'
on the server to see what it is actually doing. I'm quite happy with
the performance in Cyrus IMAP.
From the ELP backtrace, at least it seems clear that the it is not
something else in Gnus that is taking all the time.
You could (setq imap-log t) as well, to study the IMAP protocol
exchange, perhaps you can spot something to optimize.
Make sure you have the agent enabled (it is on by default) or enable
the nnimap NOV cache (enabled if the agent is disabled by default).
Also check that the nnimap server is agentized.

Is the agent safe to use with nnimap? Disabling the agent seems to
have prevented all my ticked messages from occasionally becoming
unticked. I've also read that the agent can cause messages in nnimap
groups not to be expired correctly.

Simon determined in the end that I had a slow IMAP server. I'll be
switching to Cyrus or Dovecot soon and that should make the
difference.

I also had problems with the agent and disabled it after verifying
that the nnimap slowdowns were happening with or without it. I
agentized my nnimap server from the server buffer, exactly according
to the manual.
I noticed:
- the highlighting was strange, everything was sort of purple
- I lost ticked articles on one visit to a group, but they came back
on the next visit
- the agent would check thousands of messages every time I moved a
message to another group or quit the current one
I'm not sure what I did wrong, but I don't believe I have an unusual
setup except for using spam.el and gnus-registry.el maybe. I'm
running without the agent and everything seems normal again.

I'm using the agent with nnimap alot, and I have never seen ticked
messages become unticked. I don't use expiring though.

I also use the agent with nnimap. Never saw ticked messages become
unticked. I did see lossage of expiry marks, but that hasn't happened
in a while, i.e. several/many weeks (loosely follwing cvs in the
time).

What made me stop using agent on nnimap, was that when I read mail
with Gnus one one machine, the ticked articles may(*) not be available
when opening the nnimap group with Gnus on a different machine.
The articles were available on the machine they originally had been
ticked on.
Since I stopped using agent, I can always see all ticked articles from
both machines.

I recall seeing that in earlier days as well. However, I have not had
that happen to me in a fairly long while now. It may be a bit of
luck. I turn off the agent when using a particular client machine on
which my home directory has a strict quota; perhaps there's a problem
if there are multiple agent caches involved though I don't see why
that should be. For me, all tick, dormant, read and other marks that
result from any client are always seen on the others, even when the
group buffer gets it wrong when I forget to copy my .newsrc.eld file.

I didn't copy the .newsrc.eld. Completely different files in my
case. They just happened to contain some nnimap groups on the
server.
