I'll quote what Michael wrote in reply to your other thread:
... few of us would have any working knowledge of SIMCTL or VNUML. I don't.
- to monitor container cpu usage for the container there should be
lxc-top, but it might or might not be compiled for your distro.
- to monitor memory usage, there's "lxc-cgroup -n CONTAINER_NAME
I'm guessing that when running the same processes with the same
workload, a container should have lower cpu and memory usage compared
to UML, due to the fact that container does not run its own kernel.
How MUCH lower, however, is something you have to test yourself.
