I ran a test and I found unexpected results favoring mload delete over insert-select.
wall time in secs (mload = 75, insert-select = 2160)
The table had 500 mill rows and I was deleting 100 mill (20%) on a WHERE on a non-PI column date column. There are no SIs, and there were no blocking during the runs. I am using V2R4.1
What could explain the above results?
