My longest ever render is 90 hours in Vue 5 :S (my own fault for turning on global radiosity and lots of volmetrics lol) In P5 I would say 9 hours is about the longest but that is the exception not the rule, on average I would say 1.5 hours for an A4 sized pic at 300 dpi. Your render seems to be quite large (poster sized) which is probably why it is taking so long. Spec: P4 2.2Ghz, 1Gb RAM, Quadro4 Pro750XGL workstation card. Oh, also if you have a new-ish computer with a hyper-threading processor then poser will only use one thread. To get the most from your processor you should disable the hyper-threading for poser rendering.
