Oracles Releases Updated "bpftune" For BPF-Based Auto-Tuning Of Linux Systems

([Oracle] 6 Hours Ago bpftune)


The past few years Oracle has been working on [1]bpftune as a solution for BPF-based, automatic tuning of Linux systems. Bpftune has been available via Oracle Linux and GitHub while finally their open-source GitHub code has seen the first new tagged release in a while.

The bpftune daemon supports auto-tuning of Linux via BPF observability. With bpftune there is continuous monitoring of the Linux system and adjusting of system behavior at a fine-grain level. A big emphasis on bpftune is making it easier to manage the large range of sysctl tunables with the modern versions of the Linux kernel.

Bpftune 0.4-1 was released on Friday with better reliability of tuners, net buffer and UDP tuners, and improved cleanup handling around process start/stop.

With bpftune 0.4-1 is also basic Debian packaging support, fixing i386 builds, other new tunables identified, documentation updates, and other enhancements.

Downloads and more details on the bpftune 0.4-1 release via [2]GitHub .

Brief History Of Linux (#22)

RMS had a horrible, terrible dream set in 2020 in which all of society was
held captive by copyright law. In particular, everyone's brain waves were
monitored by the US Dept. of Copyrights. If your thoughts referenced a
copyrighted idea, you had to pay a royalty. To make it worse, a handful of
corporations held fully 99.9% of all intellectual property rights.

Coincidentally, Bill Gates experienced a similar dream that same night. To
him, however, it was not a horrible, terrible nightmare, but a wonderful
utopian vision. The thought of lemmings... er, customers paying a royalty
everytime they hummed a copyrighted song in their head or remembered a
passage in a book was simply too marvelous for the budding monopolist.

RMS, waking up from his nightmare, vowed to fight the oncoming Copyright
Nightmare. The GNU Project was born. His plan called for a kernel,
compiler, editor, and other tools. Unfortunately, RMS became bogged down
with Emacs that the kernel, HURD, was shoved on the back burner. Built
with LISP (Lots of Incomprehensible Statements with Parentheses), Emacs
became bloated in a way no non-Microsoft program ever has. Indeed, for a
short while RMS pretended that Emacs really was the GNU OS kernel.
