Thanks for the change. By the way I meant when doing Vendor config and customer workflow config. To implement that requires nested config file. In other words the set-performance.conf, then a file for instance in a set-performance.conf.d/custom.conf (or similar). The custom.conf in the conf.d directory overrides the same property as well as section within set-performance.conf.

@john.c Great ideas (especially if Vates decides to bake something similar into XO someday) but may be getting too far into the weeds for now...

That’s okay. Just putting it out there - no rush! Any way to maintain Linux good practice relocate the conf file to /usr/local/etc/ (or /etc) then keep script in /usr/local/bin.

@johnnezero Also there’s shortcut directories including one called cron.hourly, you can place a symlink (or hard link) to the script there. Cron will then execute the script without you needing to alter the crontab file.
Just drop .sh for using the shortcut directory as it will not run there otherwise.

@john.c Yet another awesome idea - adding it to the "ToDo List", thanks!

@john.c Wandered off through the weeds (with Claude/AI that us), and got it done.
-
@john.c Also done! Thanks for all the great input, keep em' coming...

@johnnezero this could be a plugin in XOA !

@Pilow Sounds like an awesome idea. Send any details you may have on how to make plugins (if you know how that is).
Adding to the ToDo list - Thanks! -

How’s your JavaScript (Typescript), JSON etc? These are the languages needed to develop plugins for Xen Orchestra.

@johnnezero It would be also interesting to take UMA/NUMA into account as VMs -- in particular, VMs with vGPUS -- can run much more efficiently if they do not cross memory bank boundaries that span more than one CPU instance. On some Linux systems -- not sure about the one hosting XCP-ng -- you can even disable NUMA. Just an additional thought here. I published a number of years ago a three-part series "A Tale of Two Servers" discussing a number of related optimizations but alas, the Citrix blogs were eliminated and I'm snot sure where copies of these articles exist anymore. But there are plenty of articles on this, in particular by Frank Denneman, and also ones like the following;
