right now my cms is 2D, and indeed most of the graphics are static then. but i have plans to lift it into 3D, with "rooms" interacting via avatars, and then the graphics-selection and avatar-behavior (animations) selections alone i suspect will put much extra stress on the servers. especially if i have to use sql servers to handle the datastreams. > >> oh, and the fact "cloud computing" is becoming more and more of a buzzword >> in the industry. > > Cloud computing really doesn't mean what you think it means. its a flexible term eh.. others' definitions are clearly not always aligned with yours. > >>> I wouldn't say I belonged to any particular camp at the start of this >>> thread, but now, having read what my betters have said, I'm inclined to >>> agree that threading isn't the magic wand that you seem to think it is.
