That's what we're doing, too, though the delta is still there. The bonus is that you can set up a distributed index with the number of agents equal to the number of CPUs, like described here, to take advantage of all CPUs in the server. However it's more of a manual operation, it would be hard to generate a partitioned sphinx.conf automatically.
