Hi You can find more information about performance here https://speakerdeck.com/prasanthj/orc-2015-faster-better-smaller?slide=10
Original JIRA has more initial performance numbers https://issues-test.apache.org/jira/browse/HIVE-4123 As you can see from the slides, several performance improvements went it later on. Also the slides were prepared in 2015 after which more perf improvements went in. I don't think anyone benchmarked RLEv1 vs RLEv2 after the initial perf tests.
