 enables users to view data both as a graph and as
 collection (i.e., RDDs) without data movement or duplication. By
 incorporating recent advances in graph-parallel systems, GraphX is able to optimize
-the execution of graph operations. In preliminary experiments we find that the GraphX
-system is able to achieve performance comparable to state-of-the-art
-graph-parallel systems while easily expressing the entire analytics pipelines.
