Linux 3.9 Through Early Linux 3.13 Kernel Benchmarks
Kicking things off with some disk benchmarks, the Threaded I/O Tester performance had regressed on the Linux 3.13 kernel for this SSHD system. However, the other disk benchmarks didn't appear impacted in this configuration. We still have to do our usual Btrfs/EXT4/XFS/F2FS file-system benchmark comparison on Linux 3.13 so stay tuned for further disk benchmarks.
PostMark had its best time on the Linux 3.9 kernel.
Now onto the most exciting area... graphics. With OpenArena the best days are on the Linux 3.12 kernel and newer. The main reason for this huge performance increase for the Radeon DRM driver with the HD 4870 graphics card is due to the P-State Intel driver being used over ACPI cpufreq on Linux 3.12+. I've already written several articles about the big Linux 3.12 performance change.
