Re: Wiki update

I suspect what lilith means is if you use RAM-backed storage instead of Disk-backed storage, that might reduce wear and tear on your SSD. So using tmpfs/SHM for transient data instead of your SSD is probably a good idea. Yes, but /dev/shm is a tmpfs even if you haven't mounted it so in fstab, it's ...

What without the entry?


Wow, that's quite a lot more than I see, still only 80MB..

Try without the fstab entry and I don't think it will change anything at all.

Yes, have a look with "ls /dev/shm"

I don't understand how it could have anything to do with your SSD.

Re: Wiki update

I have "size" in the fstab to define the maximum RAM usage. The gcc can also occupy 512 GB RAM. I'm wondering if internet RAM wouldn't be the better solution https://www.cs.swarthmore.edu/~newhall/nswap2L.html . I'm not sure I understand, AFAIK this has nothing to do with gcc, swap space ...

Re: Wiki update

JACK uses it by default and it was added as a config option for the kernel back in 2.x. IIRC, back then JACK used /tmp, but was changed to use /dev/shm when that became a standard feature of the kernel. IMO there really isn't any reason at all to bother with this, unless you really are paranoid and ...

Re: Wiki update

FWIW & IIRC /dev/shm defaults to half of your ram as do the other tmpfs that you have mounted. Changing this is probably mostly useful if you want to limit how much an app can use, not that I've ever seen one actually using much at all. If you don't need to either make it smaller nor bigger then...

Re: Live mixing with Linux - State of the art 2018

The only difference between Win10 and Linux is that the performance meter of Reaper reports xruns in Linux and no xrun at all in Win10. But what you hear out of the audio is the same at 32 and 64 samples with both systems: krkkr, kzzz, shrshr... That's because even though there is an ASIO callback ...

Re: One month and counting without the RT kernel on Arch Linux

I was also surprised the other day testing it.

FWIW, the main distro kernel is lowlat and doesn't really patch anything that could impact this in anyway. Still there have been some changes in the kernel config that I suspect could have had a positive effect.

Re: Is the limitation me, or ffado support for my Saffire Pro 24 DSP?

Heh, don't know why I read your post as referring to a pro 40 and not the pro 24... Still I'm afraid that I can't really offer any help in this respect as I've never tried the device. If you need help with other stuff though, I'll try to contribute with my meager understanding :) What I meant with h...

Re: Is the limitation me, or ffado support for my Saffire Pro 24 DSP?

IMO on linux the cards with the best low latency are either PCI/PCIe or FW, USB seems to add quite a lot of extra latency. The latency reported by JACK and it's clients only take the buffersize and samplerate into account. To get an idea about the actual real world latency including usb/fw overhead,...

Re: CPU Load - Renoise

Reaper's RT cpu is it's internal version of JACK's DSP load. Of course it gives a slightly different result as it's measured inside the graph.

Re: CPU Load - Renoise

Well reaper is well known for it's efficiency :) Joking apart, what happens if you rec arm the tracks in reaper? Part of the reason that reaper is so efficient is the fact that it preprocesses the tracks that aren't rec armed. It calculates all the audio in advance and then mixes the channels and ap...
