efaq: Making Gnus faster

 
 11.9 How do I make Gnus faster?
 ===============================
 
 From the Gnus FAQ (SeeReading news with Emacs):
 
      If you have a slow machine, or are just really impatient, there are
      a few things you can do to make Gnus run faster.
 
      Set ‘gnus-check-new-newsgroups’ and ‘gnus-check-bogus-newsgroups’
      to ‘nil’ to make startup faster.
 
      Set ‘gnus-show-threads’, ‘gnus-use-cross-reference’ and
      ‘gnus-nov-is-evil’ to ‘nil’ to make entering and exiting the
      summary buffer faster.
