Linux 4.2 vs. 4.3 Kernel Benchmarks On Other Systems

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:

When testing there, in very few tests there were any real changes in performance:
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:

PostgreSQL appeared a bit slower in some tests.
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.
