On VMWare if you are going to create a new SQL instance with 4 processors/32GB ram as an example GuestOS and I have access to storage that is just one a big giant 800GB "Datastore" (made up of multiple drives - dont know why it was done like that instead of separate smaller ones )

Would it make any difference in "VMware" if I asked the storage/vm admins to "carve" multiple mountpoint/volumes in my GuestOS from a performance perspective in VMware. So that I'd have a virtual C:, D:, E:, F:, G, etc.. to break up Win OS, Binaries, Data, Log, Tempdb, etc. Not sure if there are optimizations in VMWare that make a difference compared to Physical Host.

Thanks for input and comments!

compare the IO statistic on the Guest and VM level and you can found where the problem is. very bad idea to keep it like this.
