Hello, It may be that the apache.org mail server stripped the attachments.
The short text version is: Run Time: ~1,500,000 ms runs main: ORC - 90,500 ms (5.9%) 1.6: ORC - 121,100 ms (7.9%) The percentage is percent of the total CPU time, the rest of the CPU time went to processing the other formats included in the benchmark framework JSON, Parquet, AVRO, etc. Thanks.
