The reason we were able to get so much information out without increasing load in the hack defined on dani-web, was soley because of the forumcache; to do the same thing for the articles hack, you will need to create an articlecache to ensure that you can get access to your information, without heavy query load.
Well, the way it is currently set up now, I am not seeing any change in load time/stress. In fact, pages are loading quicker over the last couple days, minus a few server hiccups, which are common here anyway.
