@alf yes, CPU performance mostly.
all clients are internal, so no context switching. also no need for "security" or other details in a dedicated linux embed device without network capabilities.

It's also easier for me to tweak jack2 rather than pipewire.

And finally it's nice to have these projects that in a way help maintain the JACK project.

Stuff like
https://github.com/jackaudio/jack2/compare/develop...max-dsp-load has always been missing in JACK but now added because we needed it for Anagram.
