What are these optimizations?
It wouldn't be decreased parse time, it wouldn't be decrease disk/net IO (if the
entity is used more than once, it may even be slower), it wouldn't be table sizes
(if they are constructed lazily first time they are needed), it wouldn't be the
output SAX or DOM. Allowing entities and not using them should not affect
performance.
The only thing that springs to mind is a smaller parser and factionally faster load
times, but that is not an "optimization" and (compare Xerces and XP) *how*
a spec is implemented can easily increase the footprint more than the raw
features.
