There is an overhead associated with Xinerama. The impact depends on the application, and in many cases, the graphics hardware and drivers do make a significant difference. Which graphics hardware are you using currently? There are other dual-head single logical screen implementations that do not use Xinerama, such as TwinView(TM) available with NVIDIA's binary Linux drivers, and some other merged framebuffer modes showing up in other drivers.
