Some of the virtualized environments seem to still be an issue.
The perhaps bigger problem is what do we do with the results. I can, for example, take all of the Xeon E5-2650L V2 results, but I would not want a VPS to be a part of it. These VPS/ cloud instances often do not use a full CPU core. Amazon is famous for this because they had a measure of performance that equaled a EC2 compute unit. That EC2 compute unit scaled across different underlying CPU architectures for basic math.
Maybe what we need is a if virtualized ( ask for user input on the instance type).
Hyper-V is another great example. It may have a processor detected correctly but depending on the workload running on the overall platform, you may get different performance results.
