zhengruifeng commented on issue #24555: [SPARK-27656][GraphX] Safely register class for GraphX URL: https://github.com/apache/spark/pull/24555#issuecomment-499433712 @srowen I locally tested on some small datasets, and find the difference is tiny. However, it seems that kryo register is enable in graphx's 'benchmark' `SynthBenchmark`, so I think this will help improve perf.
