🔑 增強重點摘要

  • •The RAM increase is primarily driven by the integration of more aggressive background telemetry and the transition to a default Wayland-based desktop environment that utilizes more memory-resident caching.
  • •Canonical has optimized the kernel for 26.04 to better handle modern web browser memory footprints, which have grown significantly since the 2018 benchmark baseline.
  • •The 'Resolute Raccoon' release marks the first time Ubuntu has officially deprecated support for legacy 32-bit UEFI bootloaders in the installer, shifting the minimum hardware profile toward 64-bit UEFI systems.

🛠️ 技術深入

  • •Memory Management: The 6GB recommendation accounts for the increased overhead of the new 'Snap-first' architecture, which utilizes compressed memory (zswap) by default to mitigate swap-to-disk latency.
  • •Kernel Version: Ubuntu 26.04 ships with Linux Kernel 6.14, which includes improved memory management for low-RAM scenarios, though the base footprint of the kernel itself has increased by ~15% compared to the 24.04 LTS release.
  • •Desktop Stack: The move to GNOME 48 introduces a more robust indexing service for the file manager (Nautilus), which is a primary contributor to the increased baseline RAM usage during idle states.

🔮 前景展望基於引用來源的 AI 分析

Ubuntu will mandate 8GB of RAM for the 28.04 LTS release.
The current trend of increasing system requirements by 2GB every two LTS cycles suggests a continued trajectory of higher baseline resource consumption.
Canonical will phase out support for hardware with less than 4GB of RAM by 2027.
As the recommended specs rise, the gap between minimum and recommended hardware is becoming unsustainable for a smooth user experience, likely leading to a hard floor increase.
