What's the extent size? One of the things that can limit multiblock reads is an extent boundary.

Subject: Strange multiblock read events


Data warehouse environment on solaris 10 with 16k db block size. Multiblock_readcount is set to 64.

Most of my multiblock reads show up as 64 blocks, however, every third read or so is 59 blocks followed by a 5 block read.

This confuses me.
