UBB.threads PHP Forum Software Community Forums UBB.classic UBB.classic 5 Support Show topics from last X days cpu intensive for higher values?

Hello on Ubb 5.47e, if I change the "Show topics from last x days" to a higher value (say, 30 days to 75 days) is it going to effect the load on the server as people go to each forum via "forumdisplay.cgi" script? Any insight would be useful Thx in adv!
