Linux 3.13 Kernel CPU Governor Benchmarks
At the request of several Phoronix readers, here are some new CPU governor benchmarks from the Linux 3.13 development kernel as of Friday.
After the performance change in the Linux 3.12 kernel pertaining to CPUfreq, Phoronix readers have been requesting more CPU governor benchmarks. I didn't have time to run a full onslaught of CPU governor tests this week and using multiple kernel versions since I'm leaving soon, but I ran some quick ones off 3.13 Git on Friday.
With a Core i7 4770K Haswell system using the P-State driver on the Linux 3.13 kernel, I tested the two governor modes offered: powersave (default) and performance. From there I ran various benchmarks under each governor setting.
Results from this quick and dirty Linux 3.13 testing can be found in the 1312136-SO-LINUX313C65 result file on OpenBenchmarking.org, but overall for this configuration there wasn't much in the way of performance changes.
