tedd,

Funny you ask this.  I have always thought the same thing.  Then just last week
I started listing to the Zend Dev Zone podcasts.  I came across this one and
thought it was very informative.

http://devzone.zend.com/article/4497-The-ZendCon-Sessions-Episode-17-SQL-Query-Tuning-The-Legend-of-Drunken-Query-Master

It is pretty long, but it contains a lot of good information.

Listen the part about how many records you can contain in memory.
