🌟 Linux Optimization Settings

🚀 Optimize Disk I/O

Add the following to your sysctl.conf:

vm.dirty_ratio = 40
vm.dirty_background_ratio = 10
vm.dirty_expire_centisecs = 3000
vm.dirty_writeback_centisecs = 500
#dev.hpet.max-user-freq = 3072
vm.overcommit_memory = 1

Apply changes:

sysctl -p

⚙️ Adjust Scheduler Settings

Optimize SSDs and HDDs with the following script:

#!/bin/sh
#cat /sys/block/sd*/queue/scheduler
for FILE in /sys/block/sd*/queue/scheduler
do
	[ -f $FILE ] || continue
	echo -n none > $FILE
done

💨 Set CPU Performance Mode

Use this script to switch CPU governor to "performance":

#!/bin/sh
#cat /sys/devices/system/cpu/cpu*/cpufreq/scaling_governor
for CPUFREQ in /sys/devices/system/cpu/cpu*/cpufreq/scaling_governor
do
	[ -f $CPUFREQ ] || continue
	echo -n performance > $CPUFREQ
done

I/O scheduler

# scheduler for non rotational, SSD
ACTION=="add|change", KERNEL=="sd[a-z]|mmcblk[0-9]*", ATTR{queue/rotational}=="0", ATTR{queue/scheduler}="none"
# scheduler for rotational, HDD
ACTION=="add|change", KERNEL=="sd[a-z]", ATTR{queue/rotational}=="1", ATTR{queue/scheduler}="bfq"

fstrim -v /

Timer

#cat /sys/devices/system/clocksource/clocksource0/current_clocksource
echo tsc > /sys/devices/system/clocksource/clocksource0/current_clocksource

ulimit -a
