Another Look At The Bcachefs Performance on Linux 6.7

Posted on by

Immediately after the Bcachefs file-system was upstreamed into the Linux 6.7 kernel I began running some benchmarks on this new copy-on-write file-system. Shortly thereafter some scalability improvements and disabling a debug option by default were merged. So with the Bcachefs work for Linux 6.7 settling down the past few weeks, here’s a fresh look at how Bcachefs is performing against the likes of EXT4, XFS, F2FS, and Btrfs.

[$] An overview of kernel samepage merging (KSM)

Posted on by

In the Kernel Summit
track at the 2023 Linux
Plumbers Conference (LPC), Stefan Roesch led a session on kernel
samepage merging (KSM). He gave an overview of the feature and described
some recent changes to KSM. He showed how
an application can enable KSM to deduplicate its memory and how the feature
can be evaluated to determine whether it is a good fit for new workloads.
In addition, he provided some real-world data of the benefits from his
workplace at Meta.

AMD EPYC 8534P / EPYC 8534PN Benchmarks – Siena Delivers Incredible Value & Energy Efficiency For Linux Servers

Posted on by

Back in September AMD rounded out their Zen 4 server product line-up with the EPYC 8004 “Siena” processors that are optimized for delivering excellent energy efficiency with leading performance-per-Watt and maximizing value both for initial server costs and ultimately the TCO. These single-socket server chips are quite interesting for a range of workloads form the edge to networking and more. In today’s article are benchmarks of the top-end AMD EPYC 8534P and EPYC 8534PN 64-core server processors and showing how they can take on Intel Xeon Platinum “Sapphire Rapids” in raw performance and blow the competition out of the water when it comes to the incredible performance-per-Watt and value.

Roundcube becomes part of Nextcloud

Posted on by

Nextcloud has announced
the “acquisition” of the Roundcube webmail system.

As a product, Roundcube has an established path to success on its
own. With opportunities remaining to be explored, a direct merger
between Roundcube and Nextcloud is not planned. Neither will
Roundcube replace Nextcloud Mail or the other way around. The
products both have strengths and weaknesses and as open source
products they already do share some underlying libraries and tools,
but remain independent offerings for overlapping but different use
scenarios. Nextcloud Mail will evolve as it is, focused on being
used naturally within Nextcloud. Roundcube will continue to serve
its active and new users as a stand-alone secure mail client.

Benchmarking Five Linux Distros Against Windows 11 On The Threadripper PRO 7995WX / HP Z6 G5 A

Posted on by

Given the interest in the AMD Ryzen Threadripper PRO 7995WX Linux performance and the benchmarks of Ubuntu Linux vs. Windows 11 on this 96-core / 192-thread workstation processor, I’ve extended that comparison to now feature five Linux distributions up against Microsoft Windows on this HP Z6 G5 A workstation for greater perspective into the results.
