Description
create a velocity plugin based on:
๐ง 2. SERVER STABILITY & PERFORMANCE โ EXPANDED
A stable minigame network must handle bursty load, multiple platforms, and VR timing sensitivity without dropping below 20 TPS.
๐๏ธ 2.1 Architecture & Scalability
๐ง Multi-Server Architecture (Required)
A single JVM instance cannot support:
Multiple minigames simultaneously
Load surges
Multiple platform quirks
Use:
Proxy Layer: Velocity (recommended) or BungeeCord
Game Layer: One server per minigame instance
Lobby Layer: Always-online hub(s)
Cluster Model
Players โ Proxy โ Lobby โ Minigame Instances โ Databases & APIs
๐ฑ Horizontal Scaling (Scale-Out)
Do not scale vertically past diminishing returns.
Options:
Static Pool: A preset number of minigame servers
Dynamic Autoscaling: Add/remove minigame nodes based on:
Player queue lengths
Round countdown timing
CPU/TPS load
Autoscaling methods:
Kubernetes (complex but powerful)
AWS Fargate, Azure Container Apps, GCP GKE
Custom script + Docker swarm
๐ Load Balancing Rules
Distribute players across servers evenly
Prefer warm servers (avoid lag spikes on newly booted nodes)
Keep capacity reserve (20โ40% headroom)
๐งฑ 2.2 Resource Isolation & Process Separation
๐งฉ Why isolation matters
One bad plugin or lag spike in a minigame instance should never:
Crash the whole network
Tank lobby performance
Drop VR frame rates
โ๏ธ Recommended Resource Boundaries
Separate JVM for: Each world-based minigame
Dedicated JVM for: Lobby/hub
Optional dedicated JVM for: Economy, chat sync, stats collectors
๐๏ธ Containerization Benefit (Optional but Ideal)
Using Docker/Podman or similar:
Limits CPU share per instance
Limits memory usage
Simplifies restarting crashed minigames
Supports safe rollbacks
๐ง JVM Configuration Musts
-Xms โ 75โ90% of -Xmx (avoid heap resizing)
GC tuned for latency, not throughput:
ZGC or G1GC preferred
Disable huge page surprises
Set per-plugin resource watchdog timeout
๐ 2.3 Monitoring, Metrics & Observability
๐ฅ๏ธ Track These Live
System Metrics
CPU per instance
RAM usage and growth rate
Disk I/O and bottlenecks
Network traffic per node
Minecraft Metrics
TPS
MSPT (milliseconds per tick)
Player count
Chunks loaded & entity count per world
Packet throughput
VR-Specific Observations
Tick jitter tolerance
Packet delivery latency
Hit timing variance
๐ ๏ธ Monitoring Tools
Prometheus + Grafana (industry standard)
Velocity Logging Extensions
Paper Timings (last-resort profiling)
Spark Profiler (deep plugin profiling)
๐จ Alerting Triggers
Send alerts when:
TPS < 18 sustained > 30 seconds
MSPT > 50 ms
CPU > 90% for > 2 mins
Memory swap risk detected
Crash loops detected
๐ฆพ 2.4 Tick Optimization, Lag Mitigation & Tuning
๐ฏ Core TPS Goal
20 TPS = smooth play
<18 TPS = visible jitter
<15 TPS = VR sickness risk
๐ฉ Paper/Purpur Settings (Critical)
Cap entity AI tick rates
Reduce hopper ticks
Lower redstone update frequency (if redstone exists at all)
Disable TNT priority unless minigame uses it
Use async chunk generation whenever safe
๐ฆ Entity Control
For public servers:
Max entities per chunk
Cap mobs per minigame (dynamic spawn rates)
Sweep dropped items aggressively:
Shorten item despawn
Merge item stacks
๐ Chunk Strategy
Limit max view distance
Java players: 8โ10
Bedrock players: 5โ8 (they request more by default)
Use:
Async chunk loading
Chunk pre-gen before launch
Disallow random exploration in minigames to avoid unpredictable chunk loads
โ๏ธ Player Movement/Teleport Stress
Avoid mass teleports in single tick (stagger operations)
Pre-load spawn chunks for teleport destinations
๐ก๏ธ 2.5 Fault Tolerance & Automatic Recovery
๐ Robust Restart Strategy
Crash-monitor watchdog
Detect JVM death
Auto-restart instance
Auto-reallocate players to fallback lobby
Rolling server restarts
Memory leak containment
Restart every X hours or at low-pop hours
๐ฏ Player Experience Safeguards
Transfer players safely:
Mid-game โ backup server if possible
Or grant compensation rewards
๐งฏ Fail Closed, Not Open
If load exceeds threshold:
Deny new joins
Slow non-essential tasks
Shed background jobs
๐งช Canary Servers
Test new builds in a hidden or staff-only minigame
Monitor:
TPS deviation
Crash rate
Memory leak signatures
โ๏ธ 2.6 Plugin & Code Performance
๐ Performance First Design Rules
No plugin should:
Do heavy file I/O synchronously
Run long loops on main thread
Make unbounded list copies every tick
๐ Async vs Sync Boundaries (Important!)
Move these async:
Database writes
Stats sync
Web hooks
Scoreboard update aggregation
NPC movement AI calculations (if possible)
Do not move:
World interactions
Block breaks/place
Entity spawn mechanics
๐ Safe Plugin Upgrade Workflow
Deploy to test environment
Run load simulation
Timings + spark profiling
Promote to prod
Monitor critical metrics first hour
๐ฎ 2.7 Cross-Play & VR-Specific Performance Factors
๐ VR Constraints
VR players rely on:
Low-latency input
Smooth state sync
Predictable movement resolution
Server must:
Avoid rubberbanding at all cost
Prioritize movement packets
Avoid network compression delays > acceptable thresholds
๐ฎ Bedrock vs Java Performance Mismatch
Bedrock clients:
Send more movement packets
Have global reach assumptions
Expect shorter input โ action latency
Mitigate:
Packet consolidation where safe
Tick interpolation compensation
Per-platform tuning:
Projectile physics
Knockback timing
Jump arc validation
๐ SUMMARY: STABILITY = ENGINEERING FOR SPIKES
A great minigame network:
expects lag before players feel lag,
isolates failures,
scales horizontally,
and optimizes for predictability, not peak throughput.
