A good example for me is nntp+news.gnus.org:gnus.ding, which has takes (or I should say took, see below) ages to visit for me.

Does this also work over the network? We recently downgraded to exchange for our news server and it generates broken NOV lines, of the type "larsi@gnus.org (Lars I) ". So I set nntp-nov-is-evil to 't' [1] and low-and-behold it seems faster! (that maybe because gnus-fetch-old-headers seems to have stopped working as well). Jan Footnotes: [1] I tried doing this in the server parameters but failed, so I set it globally.
