 * Hi, we are using W3cache 0.9.4, but this problem was endemic to several versions
   back. If we turn on “object cache” wordpress exhibits strange behaviour – post
   saves (updates) take about 1 minute even for an empty post, many other backed
   operations also are very slow. As soon as we turn object cache off, the problem
   disappears. We want w3cache to be optimied to the max. What can we do to diagnose
   it?
 * thanks
