Interesting results. Even at 540 us worst case latency the stock kernel does quite ok'ish for audio. Regarding those RT results with one core acting up: did you try to run the RT cyclictest with 3 cores? I'm wondering if sacrificing one core wouldn't actually help. It could be also a matter of RT pr...

It's CPU1 (the green line) that's letting the side down. :) The other three CPUs have a really good maximum latency -- around 50 microseconds. That's 0.05 milliseconds. It's interesting that CPU1 is so much worse than the others. Makes you wonder if there's anything tied to CPU1. If there's somethi...

I found also (empirically) that 4.19 RT is exceptionally good, but I have unfortunately not much time to join the benchmark fest. Looking at the results from the old threads on LM, it seems we are getting better: most of the results 2y ago were around 150us, now we're reliably getting below 100us - ...

Yeah, Nvidia + RT is not the easiest going combo for audio (although it seems to be working for some people). But it is not up to Arch to delay upgrades to support proprietary drivers - rather the opposite ;-) Anyway, if you want to pitch Linux-ZEN against the latest stock or RT, why not run a few b...

I think the Archlinux zen kernel is the way to go. Another plus is that it uses the newer I/O schedules like kyber/mq-deadline/bfq for better multi read/wrrite performance on HDD's. This kernel also has optimized the RCU timer threshold setting for more responsiveness. Attached is a zip I created t...

Gimmeapill do you not disable obviously irrelevant stuff in your kernel config? I used to be able to build a trimmed down one in about 10mins on my old core2duo. Yes, I used to, but this became over time a lot more pain than it is worth. I also used to build the spartan way with "make localmod...

...and in the meantime, look what just made it to the AUR: linux-rt 4.19.10 You can install a pre-built RT kernel by adding this unofficial user repository. I prefer to build stuff myself in a clean chroot rather than use third party repos whenever possible, but it is true that 4.19 RT did take a s...

@merlyn: thanks the precisions, I never looked too far into the stock Arch kernel. I should have made more clear that stock Arch <> vanilla, but anyway this is true for more or less any distro. ...and in the meantime, look what just made it to the AUR: linux-rt 4.19.10 https://aur.archlinux.org/pack...

Cool, thanks for the update!

Very Nice!

It's been a while since the last update, is the project still going?

Sorry for misleading you guys, I didn't mean to dump Ardour/Bitwig just yet Yes it is a very fresh project. The website is two days old, the gitlab master repo is getting updated daily, and there was no official announcement. But for a 6 month old one man project, I think this is pretty impressive a...

But, What are the minimun settings for audio work with stock kernel? Maybe add user to audio group and config the /etc/security/limits.conf file? This thread assumes a system already tuned for low latency audio work. (distro specific, but https://github.com/raboof/realtimeconfigquickscan is your fr...

Ha! I just had to reboot on 4.18 RT to open an old Renoise project. It is not night and day by any mean, but I have slightly less xruns (possibly also because of jack1). So 4.18 RT still has a tiny edge over stock 4.19/4.20 I would say, but it's a very close call. This makes me wonder how 4.19 RT wi...

Hi Folks, Just spotted a new DAW in the Arch User Repository (I didn't try it but from the screenshots it looks rather good). Description from the site: About Zrythm Zrythm is built using C and the GTK+3 toolkit and borrows ideas, concepts and code from other projects such as Ardour, Jalv, Bitwig an...
