The idea is that performer gives you good performance for a given geometry
description. There are some exceptions such as drawing a cylinder where
you could shave off every other surface normal in GL and you don't have
that flexibility in Performer.
Performer will also try to reduce texture binds and material binds but
can only do this if you've added your geometry to the scane graph, so
this is probably what you want to stick to. Non indexed geosets could be
faster (unless you are short of memory).
There are circumstances where you wouldn't want to add some geometry
to the scene graph but you could still build geosets and draw them using
libpr.
