I've got a new Centos 5.1 x86-64 server that uses PHP to communicate with MySQL5. On this server, PHP/Mysql connections are dead slow and unresponsive. It takes sometimes up to a minute to list tables in phpmyadmin for example.
My suggestion is just for the test and see if it will improve, try to update from RPMForge both your apache, php and mysql one at a time then test. I believe Dag's repo has more recent version.
Thanks,
