[$] An overview of kernel samepage merging (KSM)
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.
Roundcube becomes part of Nextcloud
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.
