Linux 4.2 vs. 4.3 Kernel Benchmarks On Other Systems

LINUX KERNEL
Last week I delivered some Linux 4.3 Git kernel benchmarks on Intel Skylake comparing it to Linux 4.2 stable. However, for those not yet on Intel's latest generation of processors, here are some Linux 4.2 vs. Linux 4.3 benchmarks with older hardware.

First up, I ran some Linux 4.2.0 vs. Linux 4.3 Git benchmarks on the Intel Haswell Xeon system I've been running a lot lately:
Linux 4.3 Xeon Intel Benchmarks

When testing there, in very few tests there were any real changes in performance:
Linux 4.3 Xeon Intel Benchmarks
Linux 4.3 Xeon Intel Benchmarks
Redis seemed to regress the most with Linux 4.3.

Then I ran tests on a completely different system, this time an Intel Core i7 4790K box:
Linux 4.3 Xeon Intel Benchmarks

Linux 4.3 Xeon Intel Benchmarks
Linux 4.3 Xeon Intel Benchmarks
PostgreSQL appeared a bit slower in some tests.
Linux 4.3 Xeon Intel Benchmarks
Linux 4.3 Xeon Intel Benchmarks
Like with the Xeon box, this Core i7 system also showed lighter performance out of Redis when using the Linux 4.3 kernel compared to Linux 4.2 stable.

More tests still coming. There's also the daily performance tests of the Linux kernel on Ubuntu and Fedora over at LinuxBenchmarking.com.
