For the browser case I have the feeling it is guest device I/O from one
to the other that is taking way too long, but the real problem is that
I'm not able to gauge if I am going way over time accurate speeds and
even want to bother optimising.

For the case where I am spawning vaxen on a small small box I'm CPU 
bound
host wise, and not sure when to stop.
