This cuts the other side as well: since VMs are so slow, any speedup that
can be taken should be taken. This makes the difference between overhead
factors of 10 and 1000.
Besides, VM optimizations are the most rewarding, since they will speed up
the entire software. Any optimization further up in the software layers will
have a lower payoff.

This is not an official statement from my employer.
