Linux 3.5 Through Linux 4.4 Kernel Benchmarks: A 19-Way Kernel Showdown Shows Some Regressions

Filed under

Linux

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.

An Early Look At Linux 4.16 Performance On Five Systems

Here are some preliminary benchmarks of the Linux 4.16 development kernel compared to Linux 4.15 stable on five different systems. Last week I began testing out the Linux 4.16 kernel on a few different boxes and it's been going rather well (sans the ongoing AMD Raven Ridge Linux issues...). For some initial Linux 4.16 kernel benchmarks I have results today to share for a Core i5 6600K, Core i7 6800K, Xeon E3-1280 v5, Core i9 7980XE, and Ryzen 7 1800X as a few of the available boxes for testing. Tests on other hardware and a greater variety of tests will be coming in the days and weeks ahead as Linux 4.16 continues to stabilize. Read more

Oracle open-sources DTrace under the GPL

Oracle appears to have open-sourced DTrace, the system instrumentation tool that Sun Microsystems created in the early 2000s and which has been beloved of many-a-sysadmin ever since. As noted by developer Mark J. Wielaard, this commit by an Oracle developer shows that something is afoot. Read more
