Boot with UEFI directly

Modern method. I don't use GRUB.
When updating Linux kernel pacman hook runs /etc/pacman.d/hooks/on-kernel-install. What it does:

• Moves Booster image and microcode to EFI partition.
• Updates UEFI boot entries linking these files using efibootmgr.

Dependencies

• efibootmgr
• Booster (Boot image generator. Faster, lighter than dracut.)

Automatic login on boot

Lazy to type password everytime.
/etc/systemd/system/getty@tty1.service.d/autologin.conf

Zram

It's a part of ram. Compresses ram to have more ram. Faster than SSD swap file.

• Install zram-generator
• /etc/systemd/zram-generator.conf
• Disable zswap by adding zswap.enabled=0 kernel parameter. As I manage the kernel using script /etc/pacman.d/hooks/on-kernel-install so added flag there.

Systemd logs in ram

Reduces unnecessary SSD write.

• /etc/systemd/journald.conf.d/journald.conf

• Delete existing logs:

sudo rm -r /var/log/journal/*

Blacklisting unused kernel modules

/etc/modprobe.d/blacklists.conf

BlueZ battery missing

Add --experimental flag /etc/systemd/system/bluetooth.service.d/bluetooth.conf

Remove pacman multilib

During Wine installation I added "multilib” in /etc/pacman.conf which resulted in duplicate 32-bit version of each package. I don't use Wine now.

Cleanup unused packages

List packages installed someway by you.

pacman -Qqi | grep -E "Name|Description|Required By"

Identify what you don't need reading package details.
