Oh, one other thing... Do the web programs using mysql for anything? 
I've seen mysql do some really dumb things on a 3-table join, like make 
a temporary table containing all the join possibilities, sort it, then 
return the small number of rows you asked for with a LIMIT.  Maybe it is 
better these days but that used to happen even when there were indexes 
on the fields involved and if any of the tables were big it would take a 
huge amount of disk activity.
