Re: Inhibiting gnus-get-new-news at startup

I might have spoken too soon. It appears that the issue is not with nntp
groups, but with nnrss. I ran the profile and saw the following:

It appears that much of the time was spent on fetching and parsing rss
feeds. I am using (setq nnrss-use-local t) which I expected to be much
faster, but that gnus is still very slow.

Some of you suggested to change the level of subscription to a higher
number. What are the implications of this change? I mainly am interested
in getting the list of new news of all subscribed groups about once a
day.
