We describe Currawong, a tool to perform system software architecture optimisation. Currawong is an extensible tool which applies optimisations at the point where an applica-tion invokes framework or library code. Currawong does not require source code to perform optimisations, effectively decoupling the relationship between compilation and optimi-sation. We show, through examples written for the popular Android smartphone platform, that Currawong is capable of significant performance improvement to existing applica-tions.
