Well, it's easy enough:

I just open the "gmane.linux.kernel" newsgroup (obviously the new
server here is gname). When gnus asks for how many articles  from this
group I want, I just answer 10000 (yes ten thousand).

So now wait for the summary buffer to appear. Once it's done, you can
play with the limiting article commands for example (like / s to limit
to articles with a particular subject). And normally you can notice
that gnus is almost unusable.

This is with threaded view:
      (setq gnus-thread-sort-functions '(gnus-thread-sort-by-most-
recent-date))

This is with Gnus v5.13 on a quad core with 2 Go...

Thanks
