I finally bit the bullet and added the WP-Cache plugin to the site. I do not have a response time problem but this should help if I every get Dugg. I was a little concerned it might break things. Some folks are big fans and others says it causes more problems than it is worth. So far everything has worked as expected. Hopefully this is the end of my blog plugin changes.
