reading nntp

[Gary Wessle]

Hi
I am running v5.9.0, in the Group buffer then I place the pointer over
an item and hit <RET>, the mini buffer gives me the option weather to
accept the (default 2395) which I then either hit <RET> or type in a
number say 300 <RET>, but in either selection it takes the same amount
of download (nntp read: 680K).
is it not suppose to take less time for 300 than the default of 2395?

here is my gnus.el
****************************************************************
(setq gnus-select-method '(nntp "news.iprimus.com.au"))
(setq gnus-check-new-newsgroups nil)    ;save time at startup
(setq gnus-fetch-old-headers 'some)     ;prevents teared threads
(setq gnus-posting-styles
      '((".*"
         (name "Gary Wessle")
         (address "phddas@yahoo.com"))))
(setq gnus-extract-address-components
      'mail-extract-address-components)
****************************************************************

thanks
