[otrs] Default install of OTRS + LDAP auth WITH mod_perl major performance issues

Ok, I have a fresh Redhat ES 5 server box. I have OTRS 2.2.5 and im trying to use ITSM. I have only set up LDAP authentication, and made sure mod perl is running. The server does nothing else. When I go to do something like the Admin section, then Packages, it takes WAY too long or times out. I go to the OTRS demo site and its lightening fast. What could possibility be wrong? I am going to try to upgrade the latest of everything, I just cant understand how the site could run SO horrible when there no data in it. Redhat ES 5 with all patches. OTRS 2.2.5 2 GB RAM, plenty of CPU, etc, etc MySQL latest Apache 2 latest ANY thoughts?
