Exactly. Their setup must be very strange, causing extremely low 
performance. They don't disclose the gory details, so it's impossible to 
repeat what they do. I can e.g. only guess that "suspend" means "saving 
the VM state".

Not exactly what I'd call a "benchmark", because it's not repeatable by 
anyone.
