seems also to be the case on linux Hi :) I reply from my "pro-audio" (bizarre term) Linux DAW ;). Are you talking about real-time for the users? On Linux even a vanilla kernel can be used with real-time abilities + you can configure it to _full_ preemption and enable threadirqs when booting, without patching the kernel. Im using a real-time patch for my kernels, but the difference to a full preempted kernel are minimal. Usually real-time permissions are given to the user by PAM, http://www.jackaudio.org/linux_rt_config . FWIW if on FreeBSD real-time is an issue, there still is the possibility to take care about some other stuff, that could harm audio performance. On my machine I unbind some USB ports, that share the IRQ with one of my sound cards. echo -n "0000:00:13.2" > /sys/bus/pci/drivers/ohci_hcd/unbind echo -n "0000:00:13.4" > /sys/bus/pci/drivers/ohci_hcd/unbind There isn't a difference for the performance on my machine, but perhaps this can help on other machines. You can stop services, bluetooth, cups, resp. remove drivers for firewire, parallel port, printer. http://wiki.linuxmusicians.com/doku.php?id=system_configuration It's said that editing PCI bus latency isn't a good idea and IIRC it has got no impact to PCIe, but I might be mistaken. http://www.mythtv.org/wiki/PCI_Latency Using Linux for pro-audio (this term simply is for "good working audio", not only for professional usage ;) IMO still is luck of the draw, but possible and this by running jackd as user.
