relac¸a˜o de desempenho e o que pode ser melhorado no VIM on-demand comparado com o tra- dicional. Investigar problemas de alocac¸˜ao de recursos que possam surgir a transferˆencia dos snapshotspara ser utilizado em outros servidores.
Realizar estes novos experimentos, al´em de interessante no ponto de vista de verificac¸˜ao de falhas e desempenho, permite aperfeic¸oar o desenvolvimento e evoluc¸˜ao do VIM on-demand, uma vez que quanto mais testes e cen´arios diferentes, melhores validac¸˜oes podem ser dadas.
