Analysis of Distrubuted Java Application Using Dynamic Instrumentation(www.dps.uibk.ac.at/projects/aksum/publications/cluster2005.pdf) 이전에 나온 논문으로 'Aksum'에 내용을 가지고 있다. 5장의 Performance properties 에 대한 내용이 눈여겨볼 만한다.

- Inefficiency

core의 개수와 region의 execution time간의 상관관계가 없으면 inefficiency에 대한 severity는 증가한다.

- LoadImbalance

The property LoadImbalance is computed for code regions where the CPU time corresponds to at least 95% of the execution time.

- Overhead

Performance overheads reflect basic resons why a program does not perform ideally, for instance due to cache misses, excessive communication or IO operations.
