For onboard and USB devices, try Periods/Buffer = 3. The aim here is to find the best possible combination of buffer size and periods, given the hardware you have. Have I rebooted after having done all that?.See: Realtime for Users#PAM-enabled login (Pay special attention especially if you do not run SDDM, GDM or Slim.) Is PAM-security and realtime working OK?.Is PulseAudio, OSS or something else grabbing my device?.Have I set up sound properly? See ALSA or OSS.The steps below are mostly to double-check that you have a working multimedia system: VT1720/24 PCI Multi-Channel Audio Controller (rev 01) $ lspci | grep -i audio 03:00.0 Multimedia audio controller: Creative Labs SB Audigy (rev 03)Ġ3:01.0 Multimedia audio controller: VIA Technologies Inc. The SOUND_CARD_PCI_ID can be obtained like so: # setpci -v -s $SOUND_CARD_PCI_ID latency_timer= ff You may also want to maximize the PCI latency timer of the PCI sound card and raise the latency timer of all other PCI peripherals (default is 64). etc/sysctl.d/90-max_user_nf fs.inotify.max_user_watches = 600000 This again can be done on the fly with sysctl fs.inotify.max_user_watches=600000 or in a dedicated configuration file: 600000, that inotify keeps track of for your user, can help with applications, that require many file handles (such as DAWs).

  • Increasing the maximum watches on files (defaults to 524288) to e.g.
  • This can be done on the fly with sysctl vm.swappiness=10 (see sysctl(8)) or setup permanently, using a configuration file (see sysctl.d(5)) such as: 10 will make the system wait much longer before trying to swap to disk (see wikipedia:Paging#Swappiness).
  • Reducing swappiness (aka swap frequency, set to 60 by default) to e.g.
  • # echo 2048 > /proc/sys/dev/hpet/max-user-freq # echo 2048 > /sys/class/rtc/rtc0/max_user_freq
  • Increasing the highest requested RTC interrupt frequency (default is 64 Hz) by running the following at boot:.

  • Add noatime to fstab (see Improving performance#Mount options).
  • Using the threadirqs kernel parameter (consult for reference) - enforced by default by the realtime kernel patchset.
  • by installing realtime-privileges and adding your user to the realtime group).

    Setting the CPU frequency scaling governor to performance.You may want to consider the following often seen system optimizations: Only if you require a setup with lower latency and greater stability, start considering optimizations! Try a standard setup with the vanilla Arch Linux kernel first. While for some systems and setups a higher level of optimization is necessary, for most users this will not be the case. Note: The quality of information on best practices and system configuration vary a great deal (and are outdated or sometimes even contradictory in many locations).
