You might look in the manual under 'Summary Buffer >Lines' to see if can identify a simplier string; one that meets your >requirements yet offers better performance. 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. Daniel.
