The Fast Fourier Transform test also indicated a slowdown for Ubuntu when switching to the Linux 3.15 kernel. With the kernel upgrade from the official Ubuntu 14.04 kernel to the Ubuntu mainline PPA is also the switching from CPUfreq Ondemand to P-State Performance.

Further investigation will be done of these performance changes.

TTSIOD improved with Linux 3.15 from the Ubuntu Mainline Kernel PPA.

Himeno, meanwhile, regressed. Overall with these tests we didn't see too much of a change when they were rebuilt under GCC 4.9 versus GCC 4.8 for this Core i7 3960X system.

If you are interested in more of these Debian vs. Ubuntu benchmarks, more of the test result data is available via the hosted 1406044-KH-DEBIANLIN83 result file. Conduct your own Linux distribution benchmarks with the Phoronix Test Suite. Further investigation is underway with regard to many of the performance changes coming from upgrading the kernel on the Core i7 3960X EE system from using the official Linux 3.13 kernel for Trusty Tahr to using the Linux 3.15 version from the Ubuntu Mainline PPA.
