Just a follow up here since I've received an official VMware answer to this. VMware Vsphere 4 does not alter native Windows Server Scheduling.

Cluberti, Thank you for your resourceful reply, I appreciate it. Cheers!

Hello, I have a question regarding multiple single threaded processes running on a dual core (single phyiscal core) server. We have have a Windows Server 2008 R2 running as a file and print server in this environment. Since each process is only single threaded, is it useless to have dual cores as usual logic would dictate? Upon checking the resource monitor, Windows seems to balance single threads over both cores. I've researched and discussed this for a few days and have learned quite a bit but do not have a definitive or authoritative answer. I've learned in our case a file and print server can use dual cores since the Windows Scheduler will balance the threads over the multiple CPU's depending on how busy a processor is at any given time. File and print services are not multithreaded so does the OS scheduler simply handle this at a native function? I do not know if the single process for print services (spoolsv) can create multiple threads as I assumed it would when necessary. Also, does this change in a virtual environment say VMwares VSphere 4 which is a Linux Kernel passing to Win OS? VMware recommends a single processor for every VM in this single threaded scenario or there can be performance loss. So assuming appropriate CPU utilization, I'd have to split the file and print server into two separate VM's as recommended by VMware which adds an additional license than simply keeping a single VM with 2 vCPU's. Thank you.
