Yes, it feels like it doesn't it!?

I thought your first post started off running on a hypervisor. In that case all bets are off and you're subject to what the host OS will allow you to do. That puts a whole other pie in the mix. Sorry didn't mean to confuse anyone, it _is_ a hypervisor, I'm in a vm guest (both Win and Linux) and the numbers are rubbish. But I'm comparing to another system that is real hardware with the exact same test. Yes, it's all different with how the hypervisor obfuscates all the underlying hardware, I get that. My expectation is that my big fancy SAN from a vm guest is going to perform better than my home PC. My logic says that if it isn't, then something must be wrong somewhere. /AH
