To speed up updates, enable parallel downloads in Pacman by editing /etc/pacman.conf:
- sudo nano /etc/pacman.conf
- Uncomment the following line:
- ParallelDownloads = 5
- Save and exit.
3. Use the BORE Scheduler
To enhance system responsiveness, switch to BORE scheduler:
- sudo grub-mkconfig -o /boot/grub/grub.cfg
