Hello,
I have a repository with a real time kernel I use for music.
https://copr.fedorainfracloud.org/coprs/ycollet/linuxmao/
With this kernel, I can 128 samples buffer at 48kHz and 5 ms latency
without Xruns.
I use "a lot" of applications to perform guitar (guitarix + tuxguitar).
I also can record video "live".
Here's an example:

Best regards,
YC

Hi Erich,
so today I spent some time in the recording session with the following
settings and configurations:
* The machine is 2x 12core Intel Xeon with an SSD drive and 32GB RAM
- I know that this is a recording overkill and I am not sure how
much the machine itself can influence the recording process.
* Soundcard is Focusrite Scarlett 2i4 over USB
* My system is an updated Fedora Workstation 32 with stock kernel (I
only lifted up the ulimits)
* The recording session was set to 48KHz, 32bit float audio
* The session had about 15 tracks, out of which there were 5
sound+midi tracks and the rest were sound tracks
and I have made the following observations:
* the session could perform playback normally on 512 samples and
10ms latency
* when I recorded on 512 samples and 10ms latency, I could work
flawlessly for about 10 or 15 minutes and then, all of a sudden,
Ardour spat a bunch of xruns. I started to delete the xrun markers
one after another and Ardour crashed.
* then I restarted it on 1024 samples and 21ms latency which was
fine for the rest of the work -> did not have any more xruns.
So, I can confirm, that with the above settings I can use stock Fedora
Workstation with Gnome desktop for my recording at 1024 samples with
21ms latency.
I could not test higher freqencies, because I do not have any such a
project ready, but when I experimented with 192KHz, I was fine with
2048 sampes and 42ms latency, which I remember very well (from that
experience my settings of 2048 samples do originate from).
I hope you can use this info, if you needed something else, please let
me know.

Hi Erich ,
Sorry , I thought the primary focus was to find a new de to shift to .
Improving Gnome in terms of reducing resource usage (and in
general ) seems pretty nice . I'd be happy to have another de I
can work smoothly with :)
This might not be relevant but if you install pantheon de , you
can switch to gnome on the logout screen (even if you didn't
install it ) and it basically brings gnome shell with pantheon apps .
I felt it was a bit smoother than normal gnome ( I didn't test
this extensively but everything seemed to work fine ) .Maybe this
can help in some way ?
Thanks ,
Harsh

Hi Harsh,
I also lead Ubuntu Studio and we just moved away from Xfce to KDE
Plasma because we wanted a more-functional desktop for creative
professionals. The resource usage between Xfce and Plasma is
neglegable
(about 50MB difference) and KDE is a better choice for
graphics artists
(which Ubuntu Studio also covers.
I think you missed the point though: the goal is to help GNOME
improve.
I've had conversations with people who want to see GNOME
improve in
this regard and want to work with me in improving it. So, this
isn't
about simply switching desktops, this is about helping another
desktop
improve its situation. If Jam is to switch, it's going to
GNOME, that
decision is already made. The "If" is what I'm working on,
whether or
not to actually go through with it. If it does happen, the
goal is to
improve GNOME. One can always install whatever desktop they
want and do
"dnf groupinstall 'Audio Production'".
I hoep that clears things up, as I think you missed the point. :)
Erich
