Yes, that's strange. But the initial reporter did not complain about this, so it could just be nVidia related problem. We don't know at all what the nvidia-glx binary driver does for Compiz, so it's impossible to debug this here.
Yep this could be completely unrelated to what the original reporter experienced.
But IMHO the fact that terminal windows created before compiz is launched don't suffer from the slowdown proves that compiz *can* handle terminal windows very well on Nvidia hardware.
All these windows cohexist in a single X session, so I don't think that it's related to the way the Nvidia driver behaves. Compiz must do something to the terminal windows it creates that metacity doesn't do, the trick is to find that difference :-)
If you think (as I do now) that this is not related to what the original reporter experienced, don't hesitate to split the bug.
