comment Extremely high mysqld CPU usage with no active queries
Try running this: "mysqladmin -u root -p -i 1 processlist". That might show you short-lived connections that you're otherwise not seeing with a manual SHOW PROCESSLIST

comment Do I need a RHEL subscription to install packages?
You can install RPMs manually which is madness. Just use CentOS and stop listening to that administrator.

@ceejayoz, 1-2 seconds is okay. Depends on what your application is doing and what browser the client is using.
