Hi,
still testing AVLinux and it's working great so far. I'm using it on a persistent USB stick at the moment and I just did some tests with Bitwig to compare it to my Ubuntustudio system. In Ubuntustudio loading 10 instances of DIVA with the second preset looks like this:
In AVLinux playing the same project with the same audio settings and Jack I get this:
Before Ubuntustudio I was running Debian and I optimized the audio by myself. I never reached such a good and smooth DSP load in Bitwig (i'm using Bitwig here, cause the DSP load graph is quite illustrative) like in Ubuntustudio. I wonder what's the crucial setting here or where to look as both Distros should be optimized out of the box. Governor is of course set to performance in both cases. I wonder if the difference comes from the kernel or from some boot parameter?
If you want to test yourself you can download the Bitwig file from here: https://e1.pcloud.link/publink/show?cod ... iXJbgaji27
Both - Bitwig and Diva - can run in Demo mode. I was using DIVA VST3 from here: https://www.kvraudio.com/forum/viewtopic.php?t=564393
