Ok. You didn't mention independed mesurement.

Ok, your need CPU time, right, not IO.

VMware is much much older, developed by a payed team driven by comerical
interrest (you know EMC,the owner of VMware.)
Colinux is mainly based on vulantary (great) work of some nice 
guys like Henry et al.


But you are right:
If there is a factor of 2 to 3 in performance waste, it might be
worth a view. But 4 me "stability" is more important:
I can simply buy more GHz clocks with the next chip releases.

I think that would be a good idea, so i'll "insist" ;-)
