Yes, but I am wondering how *much* less efficient.  Trying to gauge 
whether I should go back and rewrite the code (not an easy task).  If 
it's just a "little" less efficient, I won't bother right now. 
Obviously the answer to my question is very context-dependent, but it 
seems that there are places in PHP where the execution time can be 
slowed very much by minor differences in technique (e.g. using 
ereg_replace vs preg_replace vs str_replace).

Yah, I'm already using mysql_pconnect(), so I know that each object's 
connection to MySQL is persisting.  But I am unclear on whether the 
connections are specific to the objects creating them...?

Thanks for the help!
