I installed xen-sources-2.6.18-r12 as my dom0 and the issue seems to have gone away. Will do some more thorough throughput testing on it later. I'm using gentoo-sources-2.6.31-r6 for the domU. Question; what's the typical type of performance decrease I should expect to the domU over the network? Getting around 12MB/sec to the dom0, and anywhere from 5-10MB/sec to the domU; that typical/expected?
