I'm a bit afraid of the XML-RPC overhead, parsing 10,000 small instances per second with libxml2 is doable with a bit of tuning but that's still more than an order of magnitude slower than the ad-hoc protocol and without the marshalling/demarshalling from the strings values. For SunRPC, well if you do some testing that will be fantastic.
So, you're making a guess at 100us overhead for the XML processing? That's an extra 30s with Dan's test. That really wouldn't concern me in the slightest ... If a DomainGetInfo() call is in the sub-millisecond range then it's never going to be a bottleneck IMHO. (Especially since the reason Dan is talking about XML-RPC is so that we can have notification of state changes instead of polling for them) Cheers, Mark.
