It does compress better than the xdiff lib, but the speed improvements against xdiff(1) are probably because the resulting tree is smaller. I favor the xdiff code because it's so much smaller, and seems easier for us to maintain. For performance, there's still quite a bit of tuning that can be done in terms of when and how we delta. -chris
