Optimizing System Settings

Beyond choosing a lightweight DE and managing services, there are several tweaks you can make to optimize system settings further:
  • Swappiness: Adjusting this kernel parameter can control how often your system resorts to using swap space—a crucial consideration if you're working with limited RAM.
  • I/O Schedulers: Selecting an I/O scheduler that suits your specific workload can enhance responsiveness.
  • Filesystem Choices: Opting for filesystems like Btrfs or ext4 with specific mount options can improve performance.

Adjusting Swappiness and I/O Schedulers

To ensure that your Arch Linux system performs optimally on low-end hardware, you can adjust the swappiness value and the I/O scheduler. Swappiness controls the tendency of the kernel to swap memory to the hard drive, and the I/O scheduler determines how the system reads and writes to disks. Here are the commands to set a lower swappiness value and change the I/O scheduler to 'bfq', which is often recommended for its responsiveness on systems with slower drives.

echo vm.swappiness=10 | sudo tee /etc/sysctl.d/99-swappiness.conf
sudo sysctl --system

for f in /sys/block/*/queue/scheduler; do echo 'bfq' | sudo tee $f; done

After running these commands, your system will start using less swap space, which can be beneficial for systems with limited RAM and slower hard drives. Additionally, setting the I/O scheduler to 'bfq' can improve the overall responsiveness of your system. Remember to reboot your system to apply these changes fully.

Stay tuned as we dive deeper into each of these areas in the second half of this guide!

Optimizing System Services and Processes

One of the key strategies to extract every ounce of performance from low-end hardware is to streamline the system services and processes that run on your Arch Linux installation. By default, a fresh Arch install will be minimal, but as you add software, the number of background services can grow. Use the systemctl command to review and disable unnecessary services. For instance, if you're not using Bluetooth or printing services, there's no need for these daemons to take up precious resources.

Streamline Your Arch: Service Optimization Checklist

  • Identify currently running services with 'systemctl list-units --type=service --state=running'🔍
  • Analyze the necessity of each running service for your specific use-case🤔
  • Disable unnecessary services using 'sudo systemctl disable servicename.service'🚫
  • Stop active services that are not needed with 'sudo systemctl stop servicename.service'
  • Check for services that are set to start at boot with 'systemctl list-unit-files --type=service --state=enabled'👢
  • Consider disabling system timers that are not essential with 'sudo systemctl disable timename.timer'⏲️
  • Review socket-activated services with 'systemctl list-sockets' and disable if unnecessary🔌
  • Remember to mask services if disabling them is not enough to prevent auto-starting with 'sudo systemctl mask servicename.service'🎭
  • Reboot your system to ensure changes take effect and verify the system's stability🔄
  • Regularly check for and evaluate new services after software updates or installations🆕
Congrats, you have streamlined your Arch Linux system for better performance on low-end hardware!
