tokens: It was shown that even though coarse - grain merging already had great speedups ( from 1.85 to 1.9 ) , fine - grain reuse managed to improve this values , achieving aggregate speedups between 1.39X to 1.51X on top of coarse - grain merging results , amounting to speedups of up to 2.89X. However , it is worth noting that the Smart Cut Algorithm ( SCA ) execution cost did not scale well , making this approach unfeasible for large scale setups .
