Performance Benefits of Moving from Ubuntu 20.04 to 22.04 LTS (Server Edition)

Ubuntu 22.04 LTS (Jammy Jellyfish) was released as the successor to Ubuntu 20.04 LTS (Focal Fossa), bringing several improvements in performance, efficiency, and security for server environments. If you are considering upgrading your server, here are the key performance benefits of making the move.

  1. Kernel and Hardware Support Improvements: One of the most significant upgrades in Ubuntu 22.04 is the Linux kernel. Ubuntu 20.04 shipped with Linux kernel 5.4, while Ubuntu 22.04 includes Linux kernel 5.15 LTS (or newer in later updates). This newer kernel brings several performance benefits:
  • Improved Filesystem Performance: Enhancements to EXT4 and Btrfs for better handling of large files and improved disk performance.
  • Better Hardware Compatibility: Newer drivers and improved support for the latest server-class CPUs, storage devices, and network interfaces.
  • Security and Stability Enhancements: New security patches and improved kernel lockdown features improve overall system reliability.
  1. Networking and Connectivity Enhancements: Ubuntu 22.04 includes significant improvements in networking performance, crucial for server environments:
  • Optimized NetworkManager and Netplan: Improved handling of network connections, reducing latency and increasing stability.
  • Faster Networking Stack: Enhanced TCP/UDP performance with better congestion control algorithms.
  • Latest OpenSSL and TLS Versions: Enhanced security and encryption performance for web applications and secure communications.
  • Support for WireGuard VPN: Improved built-in VPN support for secure networking.
  1. Performance Enhancements for Server Workloads: Ubuntu 22.04 comes with multiple optimizations that enhance performance in enterprise and cloud environments:
  • Improved Systemd Performance: Optimized boot times and service startup speeds for better efficiency.
  • Containerization Improvements: Enhanced support for LXD, Docker, and Kubernetes for faster and more secure container management.
  • Optimized Memory Management: Better handling of large workloads, reducing swap usage and improving responsiveness.
  • Better NUMA Awareness: Improved CPU resource allocation on multi-socket servers.
  1. Storage and Filesystem Enhancements: Efficient storage management is crucial for server environments, and Ubuntu 22.04 brings several improvements:
  • ZFS and Btrfs Enhancements: Better snapshotting and compression features for improved data integrity and storage efficiency.
  • Faster Disk I/O Performance: Optimized disk scheduling for SSDs and NVMe drives.
  • Optimized RAID Performance: Better RAID configurations and improved disk failure handling.
  1. Security and Maintenance Performance: Although not a direct performance benefit, the security enhancements in Ubuntu 22.04 contribute to a more stable and efficient server system:
  • AppArmor and SELinux Enhancements: Improved security frameworks with reduced performance overhead.
  • Updated Cryptographic Libraries: Faster encryption and decryption performance.
  • Long-Term Support: Ubuntu 22.04 will receive updates until 2032, ensuring a secure and well-maintained system.

Conclusion

Upgrading from Ubuntu 20.04 to 22.04 LTS provides a noticeable boost in server performance, including better hardware support, improved network and storage efficiency, enhanced security, and a more optimized systemd environment. Whether you are running a cloud infrastructure, enterprise applications, or a local server, upgrading to Ubuntu 22.04 ensures a more secure and high-performing server environment.
