Probably depends on the interface you use.  The old umn device uses the host 
kernel as the router.  The new eth device uses a usermode daemon, but those 
packets also go through the kernel, so I'd guess there's slightly more 
overhead.

Aside from the virtuality overhead, which is there on UML <-> anything 
networking, it's basically fancy IPC, which Linux ought to be pretty good at.
