| Subj: | | Cylinder Read vs MAXBLOCKSIZE |

In V2R5 you can enable Cylinder Read, which increases I/O efficiency during full table scans of large tables (and other operations). Prior to
V2R5, you could increase I/O efficiency of full table scans by creating tables with a large MAXBLOCKSIZE. If you enable CR in V2R5, does this, in
effect, make the MAXBLOCKSIZE parameter irrelevant?
