CelestCombat-Pro v1.2.0 — Major Performance Optimization Update
Overview
This update introduces major performance improvements to the WorldGuard safe-zone protection system and fixes issues with combat command blocking.
The focus of this release is reducing CPU usage during player movement and combat interactions, making the plugin significantly more efficient on servers with many players.
Expected performance improvement: up to 90% reduction in CPU usage for safezone barrier detection.
Performance Improvements
WorldGuard Safezone Barrier Optimization
The safezone detection and barrier visualization system has been heavily optimized.
Estimated CPU usage improvement
Before ~1.60% server thread usage
After ~0.15–0.20% server thread usage
These improvements are most noticeable on PvP servers with many players in combat near protected regions.
Reduced Vertical Scanning
Barrier detection previously scanned a large vertical range.
The scan height is now limited to 4 blocks relative to the player.
Benefits:
- Reduces location checks significantly
- Improves safezone border detection performance
- Lowers CPU usage during movement events
Barrier Update Early Exit
Barrier updates now stop immediately if the barrier layout has not changed.
This prevents unnecessary operations such as:
- recalculating barrier locations
- sending redundant block updates
- iterating over barrier collections
Location Object Reuse
Location objects are now reused during scanning instead of creating new instances.
Previously each update could create hundreds of Location objects.
This change removes a major source of memory allocation and reduces garbage collection pressure.
Optimized HashSet Usage
Barrier tracking collections have been optimized to avoid unnecessary HashSet creation.
Collections are now created only when required.
Packed Cache Keys
Safezone caching now uses bit-packed long keys instead of string concatenation.
Previous cache format:
world:x:y:z
New cache format:
long packedLocationKey
Benefits:
- eliminates string allocations
- improves map lookup speed
- significantly reduces memory overhead
Bug Fixes
Combat Command Blocking
Commands defined in the combat blacklist were not always blocked due to case-sensitive comparisons.
Command matching is now fully case-insensitive.
Example commands that are now correctly blocked:
/tpa/TPA/Tpa/spawn/SPAWN
Wildcard patterns continue to function as expected.
Example configuration:
blocked_commands:
- tpa
- spawn
- team*
Technical Improvements
Object Allocation Reduction
The update removes hundreds of unnecessary object allocations during player movement events.
Key improvements include:
- removing Location cloning inside loops
- eliminating string-based cache keys
- optimizing HashSet usage
- reducing safezone scanning volume
Expected Server Impact
Example scenario: 50 players moving in combat near safezones
Before update ~1.60% CPU usage
After update ~0.15–0.20% CPU usage
This results in smoother gameplay and reduced server load during PvP.
Recommendation
This update is strongly recommended for servers running practice PvP, combat-focused gameplay, or large player counts.
Updating will significantly improve movement handling and safezone barrier performance.
