What I'm trying to do is write some support to use an nvidia "optimus"

of the is connected to physical displays).
So, any suggestions / advice / best practices (other than not buying
hardware like that) for how I should try to speed that up?

Sadly this was for an ati card where open source drivers are available
to play around with. In my case I can't really hack around in the
driver :(
And I don't want to use nouveau as I'm out for opengl performance, so
I have to use the nvidia binary blobs.
VirtualGL does what you're generally trying to do:
Essentially: GL render to pbuffer -> glReadPixels() -> XShmPutImage()
should be faster than XGetImage/XPutImage since they avoid moving pixels
over the X transport.
