Correct me if I'm wrong, but persistent connections in PHP have to do with
opening a connection between the Web Server and the Database that may be
used by multiple connections.  This allows the Web Server (e.g. Apache) to
open a single connection to the database (e.g. MySQL) instead of going
through the process of opening a connection, run SQL statement, close
connection every time someone hits a page that need to access data.  We have
found that it doesn't make that big of a difference on a low traffic web
site, but I imagine that it would if you were serving 1000's of pages every
hour.
