Of course it might avoid cylinder migrates/splits, but only for large tables which are:
- non-partitioned and you insert/delete a small percentage of the data regularly
- initially loaded (then you should also set a smaller datablocksize initially and then change back to max to avoid block splits, too)
- PACKDISKed regularly, which indicates that you're running out of perm space
And in TD13.10 there's the background activity of AutoCylPack which should replace those manual PACKDISKs.
