Maja Kabiljo commented on GIRAPH-543:
-------------------------------------
There are two benefits:
- Int, float version allows us to have bigger graph whit the same amount of
resources
- With the same graph size, new implementation was about 1.5x faster
Committing with Alessandro's +1 from reviewboard.
> PageRankBenchmark has unnecessary edge weights

> PageRankBenchmark uses PseudoRandomInputFormat, which produces edges with

> Since edge values are meaningless for the algorithm, we should change it to
> use null values to have a better evaluation of PageRank performance.
