26881 lines in the buffer " *server news.saunalahti.fi nntp *nntpd**"
which matches what I have in my .newsrc -- when I go into a group it
seems to drop to one line.

This slow-down initially started way back when I upgraded from Fedora
16 to Fedora 17. Initially when gnus tried to open the nntp connection,
it just gave the error message:

nntp (news.saunalahti.fi) open error: 'Error when connecting: 200 Elisa
USENET News Server (Typhoon v2.2.2.503)^M'.  Continue? (y or n)

I got it working by setting the following per a hint I got from the net:

(setq gnus-select-method
 '(nntp "news.saunalahti.fi"
        (nntp-open-connection-function network-only)
))

But ever since the upgrade I've been plagued by slowness.
What can I do to debug where the time is spent?
