Xara's renderer is fast, but Cairo with OpenGL is even faster.
But if Cairo gets Xara renderer, it will be just as fast.
Carl Worth (Cairo) talked a lot with the Xara programmers at the LGM. And as far as I know the plan was to make Xara's renderer GPL and then write an Caito backend.
Anyway, so far it's premature, since Xara's renderer is the part which is not opensourced yet (it remains a binary lib in their source tarball).
An other reason to use Cairo is, we will get PDF and PS export for free.

Hmm. That sounds hopeful, but I wonder how that works with Cairo's LGPL/MPL license otherwise?
If the Xara Cairo backend remained GPLed, then only GPL/LGPLed software could use that particular backend (not a problem for *us*, but...), and it couldn't replace the default software backend in Cairo (or else Cairo would be useless to non-GPLed software).

That's a good point.

I chatted with Carl a bit about this. Cairo actually has support for multiple "backends", and there are several (~5?) officially supported backends, plus a couple dozen unsupported ones. The Xara renderer could be provided as a backend that would only be available when using the GPL license option for Cairo. He said the application linking to Cairo would need to pass a string like "I am a GPL application" in order to activate it, or something like that. I also thought this was something worth checking out if it comes to be.

Rather like the GPLONLY export macros in the Linux kernel. Interesting.
