One thing you don't see often is hard numbers around the performance of virtual machines. As virtualization continues its storm into the data center and network, benchmarks and metrics are soon to be on the horizon.
Until then, a few enterprising technicians are running their own tests and results. Michal Strehovsky has a blog post about his experiences with VMware, Virtual PC and Virtual Box. One thing surprising (or maybe not) is that VMware has a clause in their EULA license that restricts anyone from publishing performance testing numbers without prior viewing by VMware. (See the blog post on Dugie's Pensieve about it.)
So which product testing or product review house, or magazine test lab will be the first to create a benchmark and publish numbers? I hope this isn't too far away. Better information means better planning for the data center and also competition between products.
Having performance benchmarks is one more step for virtualization to become even more of a reality (pun intended.)
