ecs_bench_suite fragmented_iter unexpectedly slow #759

Looking at the results in https://github.com/rust-gamedev/ecs_bench_suite, I'm surprised to see that Specs performs rather poorly in the fragmented_iter benchmark. IIUC, the Data-component uses VecStorage, and iterating over all Data-values should be a fairly quick for Specs?
