Did you try to install all the experimental.* (opaquespeedup,
contentcreation, catalogqueryplan) packages that have been done over
the last year? They help to address some of the known performance
problems.

For the particular issue at hand you can either use the opaquespeedup
package which has a more conservative approach to fixing this issue or
backport the approach taken in Plone 4 as per
https://svn.plone.org/svn/plone/Plone/branches/4.0/Products/CMFPlone/patches/speed.py
