Disclosed back in mid-November was the Intel JCC Erratum that required a CPU microcode update to mitigate and that in turn had broad performance hits. But via toolchain updates, some of that overhead can be offset. The GNU Assembler patches were quickly merged and new options exposed for helping to decrease that performance hit but on the LLVM side the developers are still working on their mitigation with some design decisions still to be made...

Introduced into the Linux 4.18 kernel back in June 2018 was the new RSEQ system call for "Restartable Sequences" to provide faster user-space operations on per-CPU data by avoiding atomic operations updates. Sadly, seeing user-space make use of RSEQ has been a slow process...

We are used to seeing tier-one Linux distributions outperforming Microsoft Windows on hardware ranging from $199 laptops to HEDT and server processors and everything in between. Thus it came as a large surprise to us when finding Windows 10 outperforming multiple Linux distributions on a new Intel laptop. Not only was Windows 10 leading, but the performance paradigm shifted that Ubuntu was even outperforming Clear Linux, which normally is the fastest of Linux distributions out-of-the-box.

One of the interesting innovations for the eBPF in-kernel virtual machine in recent times is the work by Google on supporting MAC and audit policy handling by it. This stems from currently custom real-time security data collection and analysis of Google servers internally for real-time threat protection and this patch-set is part of their work on allowing similar functionality in the upstream Linux kernel...

Being introduced by Linux 5.6 is optional F2FS transparent data compression support that was implemented with LZO and LZ4. Now for the Linux 5.7 kernel there is Zstd compression support on the way...

As part of the ZFS improvements for Ubuntu 20.04 with Canonical's Zsys initiative is the ability to automatically take snapshots on APT operations for being able to do a system rollback/revert if necessary following package management changes. I've begun trying out the ZFS/Zsys changes for Ubuntu 20.04 and so far is working well...
