We've recently upgraded our 7.5.3 FP01 environment to FP06 and the application is very slow - query response times are about double their FP01 counterparts. We've been running Oracle 10g under 7.5.3 since December without any performance issues. We've ensured there's no extra logging (on the NSA screen), and the JVMs and heaps are set appropriately. I understand some new security tables/calls are made in FP06 and, if I were to guess, that could be part of the problem. Any ideas on how to get performance to increase under FP06?
