In general I would agree, but it is very dependent upon exactly what
the virtuals are doing, what the load on them is, or what resources
they are using. However, ALL all containers, by definition, will have
less performance than a dedicated platform running the same software.

It is a waste of effort to build a complex system when you don't even
know whether a simpler system will work well enough.

Get it working first. Optimise it later.
