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 Note: The quality of information on best practices and system configuration vary a great deal (and are outdated or sometimes even contradictory in many locations).
