Какой планировщик ввода-вывода используется в вашей системе? Для ротационных носителей (классический HDD) BFQ, безусловно, лучший, если вы хотите адаптивную систему. Find out by using this command in a terminal:

cat /sys/block/sda/queue/scheduler

This will show between brackets the scheduler that is currently in use and the available schedulers on your system. If BFQ is not on the list, you will need to enable it (it is a kernel module) with modprobe:

sudo modprobe bfq

If BFQ is on the list but not selected, or you just used modprobe to install it, you can enable it as follows:

echo "bfq" | sudo tee /sys/block/sda/queue/scheduler

Check if it is being used by issuing the same cat command as we started with, it should now show BFQ in between brackets.

With BFQ as your scheduler, now try to use the same applications that took so long to open, if it is faster you can make the scheduler change permanent by creating an UDEV rule. Go to or create (if it does not exist) the following directory: /etc/udev/rules.d Open or create a file in that directory (as root) named 60-scheduler.rules Insert or add the following line to that file:

ACTION=="add|change", SUBSYSTEM=="block", DRIVERS=="sd|sr", ATTR{queue/scheduler}!="bfq", ATTR{queue/scheduler}="bfq"

save the file, next time you reboot, your scheduler will be set to BFQ automatically
