Gnus scans thousands of groups on the news server upon startup. How do I restrict it to only my subscribed groups?

Edit: This happens despite having set gnus-default-subscribed-newsgroups to true in my .gnus.el file. I have also set gnus-check-new-newsgroups to nil to no avail. I am using Emacs 27.1.

    Have you looked through (info "(gnus) New Groups") and its subnodes?

  • Why don't you submit a bug report that provides more details of your setup/server with M-x gnus-bug RET?

  • gnus-default-subscribed-newsgroups should not have any effect. Because this variable is not documented anywhere. Dec 18, 2020 at 10:53

    In the group buffer, type "A u" to see your list of subscribed groups. It could be that you have subscribed to thousands without realising it?

Gnus scans only subscribed groups on startup. To find new groups you will have to explicitly invoke gnus-group-find-new-groups which has a keybinding F in the Group-buffer.

  • This is not happening in my case. Upon startup, gnus scans all the thousands of newsgroups on the server.

    Are you sure those groups are not subscribed. Because the groups which have no new messages also doesn't appear in the group buffer but they are scanned. Dec 16, 2020 at 8:40
  • Have you played with Group Levels recently? Read about it in Gnus Manual. Dec 18, 2020 at 10:51
