That's also what an Oracle Sales Manager told me a few months ago.

Oracle engineers developed their own Linux kernel patches and sent them to Redhat to get the performance that Oracle needed for benchmarking. However, it took Redhat too long to integrate the patches into the kernel shipped with RHEL. Eventually the Oracle/Redhat partnership ended and Oracle started shipping "Unbreakable Linux" in 2006.

If you look at the TPC-C benchmark, you will find that many of the Top10 systems use the Oracle Unbreakable Enterprise Kernel to get better performance:
