Linux 3.5 Through Linux 4.4 Kernel Benchmarks: A 19-Way Kernel Showdown Shows Some Regressions
What better way to spend a cold Friday morning than looking at some kernel benchmarks, so up for your viewing pleasure today are benchmarks of every kernel major release going from the Linux 3.5 kernel up through the latest Linux 4.4 stable kernel release. All the tests were done on the same system and there are actually some interesting performance changes to note with these Linux kernel tests going back to the summer of 2012.
The system I used this week for carrying out this Linux 3.5 to Linux 4.4 kernel comparison was the Xeon E5-2687W v3 Haswell processor (10 cores plus Hyper Threading), MSI X99S SLI PLUS motherboard, 16GB of DDR4 memory, a PNY CS121 120GB solid-state drive, and AMD FirePro V7900 (Cayman) graphics card. All of the hardware was maintained the same throughout testing and each kernel was tested with its defaults as obtained from the Ubuntu Mainline Kernel PPA archive; so you can fetch from there if you are curious about any of the Kconfig and other defaults.
