Optimization is still ongoing. I'm pretty confident that the linux-aio based disk driver is at least as good. The RX side of the network driver is also pretty decent (I can get 1.5 gbit/sec). I think over time we'll be able to get a fair bit more without even going to kernel-space. Once we have a kernel space backend, I think we'll get performance that's at least as good as Xen's drivers.
