[FFmpeg-user] Advice: Running FFMPEG under VMware, performance tuning, config

We have been running FFMPEG on real-iron hardware for a while; now,
starting to run it in VMware VMs -- which is a game changer in terms of
flexibility; however, I have noticed a performance degradation -- which
I partially expected.
Understanding VMware's scheduler and how it handles CPU bandwidth is key
- for example, if you have 2 cores and a max CPU speed of 3ghz, the
speed is divided between the two cores. So, does that make two cores
more efficient than one, at full speed?
In any case, we need to expand our use of this tool under virtual
environments and I'm wondering if some of you more-experienced folks
might have some tips, advice about how to maximize performance of FFMPEG
under VMs. VMware is our primary system, but I am going to take a peek
at Xen for some development/testing.
Thank you in advance...
