You could expect a loss of 20% at I/O level by using a virtualized
environment compared to a physical server with similar hardware (rule
of thumb, number more or less general by experience). Then for
different hardwares, yes you will get performance differences...

Depends on the hardware, as well as on the environment used... It is
hard to tell without any details...
