Changelog

All notable changes to the Linux Swap Optimizer project will be documented in this file.

[2.0.0] - 2026-07-03

Added

• General Application Optimization: System now optimizes all running applications, not just AI/IDE processes
• Process Categorization: Implemented 5-tier priority system (AI, IDE, Interactive, Normal, Background)
• OS-Level Kernel Optimizations: Added dirty page ratio tuning and scheduler granularity settings
• Interactive Process Detection: Added detection for web browsers, communication apps, and media players
• Background Process Detection: Added detection for system services and background tasks
• Dry-Run Mode: Added --dry-run flag for safe testing without making changes
• Enhanced Status Reporting: Status command now shows process categories and optimization mode
• Process Priority Tiers Documentation: Comprehensive documentation for the new priority system

Changed

• Configuration Structure: Split ai_processes into separate ai_processes, ide_processes, interactive_processes, and background_processes arrays
• Priority Management: Enhanced to support category-based priority tiers with different CPU and I/O priorities
• Adaptive Management: Updated to support general optimization mode with user process detection
• Error Handling: Improved kernel parameter handling with graceful degradation for unavailable parameters
• Default Behavior: optimize_all_apps now defaults to true for general desktop optimization

Fixed

• Kernel Compatibility: Scheduler granularity parameters now handled gracefully when not available on certain kernels
• Restore Function: Enhanced to use system defaults when no original settings are saved
• Logging: Improved log level handling from configuration file

Technical Details

• Priority Settings:

  • AI: nice=-10, ionice class 1 level 4
  • IDE: nice=-5, ionice class 1 level 4
  • Interactive: nice=-2, ionice class 2 level 4
  • Normal: nice=0, ionice class 2 level 7
  • Background: nice=5, ionice class 3 level 0

• New Kernel Parameters:

  • vm.dirty_ratio=10
  • vm.dirty_background_ratio=5
  • kernel.sched_min_granularity_ns=1000000 (when available)
  • kernel.sched_wakeup_granularity_ns=1000000 (when available)

Migration Notes

• Existing configurations will automatically use defaults for new parameters
• Set optimize_all_apps=false in config to maintain legacy AI/IDE-only behavior
• Process lists can be customized in /etc/swap-optimizer/config.json

[1.0.0] - 2026-07-03

Added

• Swap parameter optimization (swappiness, vfs_cache_pressure, page_cluster, etc.)
• AI/IDE process detection and prioritization
• CPU and memory threshold-based adaptive management
• Automatic backup and restore of original settings
• Status reporting with system metrics
