Description
Reserving 3 * 8MB per column to get triple buffering is minimally useful except in the case when you're scanning a single very large column. 2 * 8MB is enough to overlap compute and I/O, and if you have multiple large columns that will mean that there are multiple I/Os in flight in almost all cases.
