RE: Physical Reads and Writes

I forgot to mention, I'm not talking about the db cache here - those wouldn't 
show up in the sar output at all, I'm talking about the filesystem buffer cache 
of your OS (unless you're using direct or raw IO).

very little chance all reads are satisfied by the database cache.
