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
