When I turned it on a highly dynamic page (lots of SQL, lots of DTML) It
got worse..

I upped that cache on the SQL and that id not really help...

I then put the test against just one of the parts of the page (that is
DTML, calls another DTML and has a SQL Select in it)

Well, that is food for thought today. If anyone has some really good
analysis of this (since this is my first time using AB) that would be
great.
