From Table 4 it is possible to verify that both Speedup and Parallel Efficiency are better for SparkBLAST when compared to CloudBLAST for experiments executed on both the Google Cloud and Microsoft Azure. This is true for both scenarios of SparkBLAST on the Google Cloud (1 and 2 cores per node). It is worth noting that even when total execution time for CloudBLAST is smaller than the 1-core SparkBLAST configuration, Speedup and Parallel Efficiency is always worse for CloudBLAST. When SparkBLAST allocates two cores per node (as CloudBLAST does) execution times are always smaller when compared to CloudBLAST.
