Ultimately fast vs inconveniently slow?

Yes.  Hmm, object density in RAM.  The CPU is not the problem.  The choice
of design for the density of the objects is.  RAM over rate=of-ID loads.

Perhaps when binding s collection for pre-load.  I don't care if it is slow
if for the cost of syntax the feature set bound is at some distribution in
the coordinate space.  IOW, how dense is the
complex/related/vector-representation of objects by proximity and rate of
motion/change.

In author space, it is the complexity of the application relationships:
objects in Ram, dull but measurable.

Markup systems cost benefits are measured by the density of consumable
relationships, ie, the possible namespaces in a wrapper hypermedia language.
Data is common.  Semantic density is king.

but it's far from obvious in advance that the two are complementing rather 
than diluting each others' best qualities in general.   Would I be right 
in guessing that you shouldn't even consider doing the gzip step if you're 
interested mainly in reducing CPU overhead?
