Al, You are correct there and We have one dedicated VFP server holding the .DBF/.DBC files which are slowly being migrated to MSSQL. The VFP server on Windows Server 2008 runs fine with 4Gb ram allocated to it and two cores with about 130 users and increasing any of these parameters yields negligible results. The defining factor is obviously the horsepower available on the server itself. We have just migrated from VMWare and vSphere onto HyperV using Windows 2012 Server as the Base O/S and the results have been excelent. HyperV allows greater flexibility in the Dynamic sizing of volumes when compared to VMWare and of course it is also free and that was a big decision in making the change as our VSphere Licence renewal was due.
All in all HyperV on our new SAN system of 3 nodes each one supporting 10 servers runs without problem. The data is snapshot automatically every 30 minutes and roll-back to older versions of data is simple, clean and quick should we need it as we can mount any snapshot as a disk and extract any files we need as well as restoring the whole environment should it be needed... again it is all free and uses 100% Microsoft tools which wasn't the case with VMWare where we needed a few 3rd party addins. Yes, we have invested a LOT ofomoney on the new SAN system but it has at least confirmed that Microsoft have got the software 100% correct for virtualisation of Win 2008, Win 2012, M$SQL and of course VFP and I can happily sleep nights now knowing that the system is 100% fault tolerant - unless of course Nuclear war breaks out in our little area of the UK .. in which case I'm outa here! If you need any help or info on HyperV or VMWare then drop me an email and I'll be happy to help where possible.

I take it each V server can choose the core it uses. As VFP can only use one core without the use of the parallelfox which is a great idea but needs a lot of planning. If the V server with the VFP app on it uses one core then it does not have to share with other apps. Logically it should speed it up.
