OK. Take a figure, say Mike3

skinhip, skintorso, skinneck ,skinarm, forearm and hand , leg and feet all use the same map
So is Poser holding 8 copies of that in memory or only 1 ?

I have a scene with only two characters and some props and I am not able to render it on a dual core 3gb system , it seems to run out of memory when loading textures.
