Nicely faster startup

Nicely faster startup

[James Cloos]

As of my last pull startup times have shrunk nicely.

I suspect most of the speedup is due to the changes to how active is
read.

Down to ~15 minutes to get the replies to the uid fetch flag calls for
each imap group, and <1 minute for gnus itself (down from ~12 or so).

Cool.

But 15 minutes!?  Are you serious?  How many groups is that?

There are a continual stream of new groups, especially under my
Bugs/Debian/, Bugs/Gnome/ and Commits/Gnome/ hierarchies.  So it
is now a bit over 21k.  (You may remember that it was 20k when
you first released the new nnimap.)

Also note that startup had become as long as 80 minutes before
you started the new nnimap and before I made dbmail-imapd's LIST
command fast.

The 15 minutes is spent servicing the examine/uid fetch requests.
Qresync will not help, since it is only an argument to select or
examine.  To get startup faster would require that LIST reply with
everything gnus needs for each listed group.  Or a box with order-
of-magnitude faster RAM, of course. ☺

Oh, right, I had forgotten about that...

Sorry to jump in to the  middle of this but my startup of gnus on my
netbook is on the order of 5 minutes whereas it's well under a minute on
my desktop.  The processor and memory specs cannot account for this
difference, in my view, but I would like to figure out where the time is
being spent in each case as the configurations are slightly different.
Can you please advise on how to do this?  elp-instrument-package gnus-
doesn't return anything useful for some reason.

Thanks,
eric

I'd suggest stracing Emacs when you hit `g'.  That should tell you what
Gnus is doing, broadly speaking.

Okay; I'll try that.  Thanks.
