LessLag

Server performance guardian for Paper/Spigot (1.20.4+) with Folia support.

LessLag is built for production servers that need stable TPS without disruptive “wipe everything” behavior. It focuses on three things:

• Detect lag early
• Explain what is causing it
• Apply safe, configurable mitigation

Why use LessLag?

• Actionable diagnostics, not guesswork
• Adaptive responses based on live server pressure
• Modular controls for entities, redstone, AI, chunks, memory, and farms
• Low overhead: workload budgeting + on-demand deep metrics

Highlights

• /lg status dashboard with health score, MSPT percentiles (P50, P95, P99), uptime, queue status, and spike counters
• /lg tickmonitor diagnostics with MSPT distribution + avg/min/max
• Lag source analysis via /lg sources and /lg trace to identify hotspots and likely culprits
• Entity management with protections for named/tamed/NPC entities
• Redstone safeguards (activation limits, clock detection, piston pressure control)
• Mob AI optimization (frustum/distance-based)
• Farm optimizations (villager optimizer, breeding limiter, density optimizer)
• Predictive optimization from MSPT trend analysis

What makes it practical in production?

• Operator-focused workflows for daily checks and incident response
• Targeted mitigation before emergency-wide cleanup
• Farm-aware controls for villager halls and high-density breeding setups
• Low-overhead telemetry model (on-demand deep stats + workload budgeting)

Useful Commands

• /lg status — live performance dashboard
• /lg health — health report and context
• /lg tickmonitor — tick/MSPT distribution diagnostics
• /lg sources — lag source analysis
• /lg trace — runtime bottleneck summary
• /lg density — density optimizer limits + suppression stats
• /lg breeding — breeding limiter blocked-event stats
• /lg reload — reload config/messages without restart

Quick Operations Workflow

1. Baseline with /lg status and /lg health
2. During spikes, run /lg tickmonitor + /lg trace
3. Use /lg sources to identify likely hotspots
4. Mitigate minimally (/lg clear hostile, /lg ai disable) only when needed
5. Tune one module group, then /lg reload
6. Validate recovery through MSPT percentile and spike trend improvements

Tuning by server style

• SMP: keep balanced defaults, tune entities/chunks gradually
• Farm-heavy/Skyblock: prioritize density + breeding + villager modules
• Lobby/Minigame: emphasize chunks/world-guard and notifications

Permissions

• lesslag.admin — full command access
• lesslag.notify — receive performance alerts
• lesslag.setup — setup advisor access

Compatibility

• Paper/Spigot 1.20.4+
• Folia supported
• Compatibility toggles for common optimization plugin stacks

Install

1. Put LessLag.jar in your /plugins folder
2. Restart the server
3. Configure plugins/LessLag/config.yml
4. Run /lg status and /lg setup to verify baseline
