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 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
