I know, it is confusing. The information section you now see on https://moodle.org/mod/forum/post.php?forum=94 were supposed to be the header of this, Hardware and performance, forum https://moodle.org/mod/forum/view.php?id=596. (I am sure because I wrote it following the German "Moodle-Technikforum" https://moodle.org/mod/forum/view.php?id=949 ;
Then our community manageress found it too much for the poor help seekers here, and pruned it (and other forums) to the present ten-word formula. Now I have the privilege of explaining the story (repeatedly) and still maintaining the original page by proxy. (See https://moodle.org/mod/forum/discuss.php?d=322223.)
Coming back to the relevance of that info, if you've seen "Please include as much background information as possible about your hardware, the operating system, the web server, the database server, the PHP scripting framework, etc." the helpers wouldn't need to pull that information one-by-one from you.
