I'm no Domino person (our Midrange Server guys are running the benchmarks), but they showed me a display that they say demonstrates that Domino recognises that there are 2x CPU's.
My understanding from measuring Domino is that it a single "chunk of work" (deliberately vague term) in Domino is restricted to use only one CPU. In some workloads Domino runs multiple "chunks" (like serving users and replicating databases in the background). For such a workload it *could* be an advantage to define the virtual machine with 2 virtual CPU's. But there is a performance / scalability penalty for defining multiple virtual CPU's, so you only want to do that when you can enjoy the benefits. You need to measure to make the right decision. You may find that the performance tools you mentioned do not help you enough to do this because virtualization effects confuse the cpu measurements inside Linux.
