Re: Poor Xinerama Performance
Upon some further investigation:
Two screens with TwinView are fine. Performance is good.
Six screens in a 2x3 grid using TwinView AND Xinerama are also fine and performance is little different from just two screens and TwinView. Just to clarify the setup here, Xinerama sees just three screens with TwinView combining each of three pairs of screens into one screen.
Six screens in a 2x3 grid using Xinerama only are very poor. Xinerama, in this case is presented with six individual screens. Performance is terrible with Java swing apps and poor with Firefox.
This seems to suggest that the problem may not be just with Xinerama, but quite possibly with the Nvidia driver.
TwinView plus Xinerama is not a viable option, as applications cannot find physical screen boundaries.
