[FFmpeg-user] Performance tuning FFMPEG under VMware

We have been running FFMPEG on real-iron hardware for a while; we're now 
trying it under VMware VMs.  I've noticed a performance degradation -- 
which I partially expected.

There are lots of folks out there running FFMPEG like this, in large 
transcoding farms (Yahoo/Google?) so I'm hoping for some really useful 

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?

Thank you in advance...
