It indeed improves somewhat the performance but it is still far
from usable. Here are the settings I have used and the time to load
headers into a summary buffer (the group contained 12000
headers):

(setq gnus-summary-line-format "") - 1 min. and 8 sec.
(setq gnus-summary-line-format "\n") - 1 min. and 8 sec.
(setq gnus-summary-line-format "%s\n") - 1 min. 37 sec.

Setting gnus-show-threads to nil doesn't make any noticable
difference.

Using any other formatting options pushes loading time still 
higher. No matter what I tried, it doesn't take less then 2 minutes
to load the group, even if the most basic usable summary formatting
line was used.

Is there are other ways to speed up the process?

BTW, my computer's specs are:

CPU: Athlon 1333, RAM: 768MB.
