Optimization

zAuctionHouse has been designed and developed from the ground up to handle very large servers. Performance has been a core priority throughout the entire development process, not an afterthought.

Built for ScaleCopy Anchor Link

Whether you're running a small survival server with a few dozen players or a massive network with thousands of concurrent players, zAuctionHouse is engineered to maintain optimal performance under any load.

Design PhilosophyCopy Anchor Link

• Async-first architecture - All database operations run asynchronously to never block the main thread
• Efficient data structures - Carefully chosen algorithms and data structures for minimal memory footprint
• Smart caching - Intelligent caching strategies reduce database queries
• Lazy loading - Data is loaded only when needed, reducing startup time and memory usage
• Connection pooling - Optimized database connection management for high throughput

Internal Performance ToolsCopy Anchor Link

zAuctionHouse includes built-in tools for developers and server administrators to measure and monitor performance.

Debug ModeCopy Anchor Link

Enable debug mode in the configuration to see detailed performance metrics:

debug: true

This activates internal timing measurements that help identify any performance bottlenecks.

Test Data GeneratorCopy Anchor Link

The plugin includes a powerful test data generator that allows you to create large amounts of test items to stress-test your server configuration.

Command:

/zah admin generate <amount>

This command generates fake auction items, allowing you to test how your server handles large volumes of data before going live.

Performance BenchmarksCopy Anchor Link

We have conducted extensive benchmarks to ensure zAuctionHouse performs well under heavy load.

Sorting 100,000 ItemsCopy Anchor Link

One of the most demanding operations in an auction house is sorting large numbers of items for display. We tested sorting 100,000 items simultaneously.

Test EnvironmentCopy Anchor Link

The benchmark was conducted on the following hardware:

Real-World PerformanceCopy Anchor Link

zAuctionHouse is actively used on some of the largest Minecraft networks, handling:

• Thousands of concurrent players
• Hundreds of thousands of active listings
• Millions of transactions per month

Optimization Techniques UsedCopy Anchor Link

1. Indexed database queries - All frequently accessed columns are properly indexed
2. Batch operations - Multiple database operations are batched together when possible
3. Memory-efficient serialization - Items are serialized using optimized byte formats
4. Thread-safe operations - Concurrent access is handled efficiently without locks where possible
5. Pagination - Large result sets are paginated to reduce memory pressure
6. Selective placeholder resolution - Item lore placeholders are pre-detected at configuration load time. At render time, only the placeholders actually referenced in the lore template are computed. For example, the default expired-item lore only uses %time-remaining%, so the plugin skips computing %price%, %seller%, %status%, and all other placeholders — saving CPU and memory per item rendered

MonitoringCopy Anchor Link

Server TPSCopy Anchor Link

Monitor your server TPS when the auction house is heavily used. zAuctionHouse should have minimal impact on TPS due to its async design.

Database PerformanceCopy Anchor Link

For MySQL/MariaDB, monitor:

• Connection pool usage
• Query execution time
• Table sizes

Memory UsageCopy Anchor Link

The plugin is designed to be memory-efficient, but monitoring Java heap usage during peak times is recommended for very large installations.

ConclusionCopy Anchor Link

zAuctionHouse is not just another auction house plugin - it's a performance-engineered solution built for the demands of modern, large-scale Minecraft servers. The 45ms sorting time for 100,000 items demonstrates our commitment to delivering a plugin that won't slow down your server, no matter how popular your auction house becomes.
