RE: vmware & Oracle

I have no experience with it, but this comment from the list archives indicates that vmware slows down I/O by adding an extra layer between Oracle and the disks:

I'd be curious to see specific numbers from someone running a fixed set of Oracle I/Os (e.g. a large table scan & a large index range scan) against the same hardware with and without VMWare. Anyone on the list done anything like that to get precise timings?

Has anyone had much experience (good or bad) with running their Oracle DB's on the "vmware" product from VMware Inc.
