With yesterday's article about the NUMA improvements to FreeBSD's network stack made by Netflix in their quest to serve 200Gb/s encrypted video content per server, in no time the forum comments were quick to theorize whether those changes would work their way back upstream to all FreeBSD users or due to the BSD license would be held as a guarded secret by the company. Fortunately, Netflix continues to impress when it comes to their open-source contributions...

Several weeks ago we wrote about a kernel fix for Linux 5.4 to address performance issues for highly-threaded Linux software running under CFS quotas. The fix can yield up to a 30x improvement in performance and one company estimated the impact of the bug cost them at least $1.5 million USD in extra resources/hardware. But now it looks like it will soon appear in a Linux 5.3 point release and possible back-ports to earlier kernels...

Drew Gallatin of Netflix presented at the recent EuroBSDcon 2019 conference in Norway on the company's network stack optimizations to FreeBSD. Netflix was working on being able to deliver 200Gb/s network performance for video streaming out of Intel Xeon and AMD EPYC servers, to which they are now at 190Gb/s+ and in the process that doubled the potential of EPYC Naples/Rome servers and also very hefty upgrades too for Intel...

IBM developers and others continue exploring the potential for address space isolation in the Linux kernel to reduce the risk of leaking sensitive data in attacks like L1 Terminal Fault (L1TF), MDS, and other vulnerabilities. Though this does increase the complexity of the kernel code and the performance hit is still to be evaluated...

The performance of Fedora 30 on multiple systems has generally been coming up short compared to the likes of Ubuntu, Clear Linux, and openSUSE Tumbleweed. With this week's release of Fedora 31 I was hopeful that the performance would be more competitive to other prominent Linux distributions, but sadly that doesn't appear to be the case. Here are some initial benchmarks of Fedora Workstation 31 compared to Fedora Workstation 30, Clear Linux 31450, and Ubuntu 19.10.
