That has been my experience as well. This has been with IBM's AIX
micropartitioning. It's not even getting into stuff like vmware.
Apparently, that kind of tech doens't work well for multiple virtual

I've done this sort of thing on "super beefy servers" and was left unimpressed.
NUMA systems can be cool. But there you still have multiple machines. They're just
all in one chassis stacked on top of each other like lego blocks.
