It's just odd that MS would use a Windows system to host files (or anything else) with all of the restrictions and limitations associated with Windows. Maybe that is the reason they over promised and under delivered. It should be common knowledge by now that unix based systems (Linux, BSD) are more efficient. There is a reason why 90+% of internet services are non-windows. Administrators don't just pick those systems out of a hat. I thought they figured that out and used unix based systems for under the hood for Azure.
