Using meta-objects to support optimisation in the Apertos operating system
Rodger Lea and

The Apertos OS has explored the use of the meta-object model and reflection
as a means to build highly flexible operating systems. While the benefits
of such a system are great, the performance cost of a clean consistent use
of the meta object model is high. Our initial work accepted this because
of our desire to explore the model to its fullest. Recently we have turned
our attention to optimisation techniques. Our work is interesting because
we have tried to use the flexibility of the model to support our optimisations.
This is in contrast to many systems that restrict or even compromise their
initial model for the sake of performance. This paper outlines the Apertos
system and discusses the optimisations we have made.
