Intel Skylake Core i5 Performance Doesn't Appear Impacted Yet By Linux 4.3
While the scheduler change could affect the performance of SMP workloads, at least for this Core i5 system the benchmarks ran today weren't impacted one way or another. The ACPI/PM code also landed and likewise there didn't seem to be any difference with the CPU benchmarks carried out compared to Linux 4.1.0 final.
My data can be found via this OpenBenchmarking.org result file but there isn't much to look at yet with no changes having landed yet in Linux 4.3 to shake-up the Core i5 6600K performance compared to Linux 4.1.0. Disk and graphics tests along with other benchmarks on this system and several others will be carried out once the merge window is over in two weeks. There's also the daily Linux kernel Git benchmarks every day over on LinuxBenchmarking.com under Ubuntu and then also the Fedora Rawhide Nodebug kernel tracker.
