Moreove, we have found that DBI causes quite lot of overhead, which
might be very important for a live site. We have been using a

sites (www.focusmag.gr) based on the application server, lead us to
try and optimize anything we could. We noticed dramatic increase in
db-specific parts of our code by removing DBI and directly accessing
MySQL with ruby-mysql. One major problem seemed to be the conversion
of results to Row instances...
