I'm finding that hard to believe too.  There isn't any "secret sauce"
in the RHEL build process --- the CentOS guys should have been able to
duplicate the RHEL RPMs exactly.  Now it's possible that CentOS had
lagged in updating some performance-relevant package; did you compare
package versions across both OSes?
