Efficiency: Near-linear scaling with proper JVM tuning. Doubling resources yields ~2x throughput when optimized.
Optimization Recommendations by Workload
🚀 API / REST Services
- Critical: G1GC with MaxGCPauseMillis=200
- Critical: Heap = 50-70% of RAM (-Xms = -Xmx)
- High: Connection pool sizing (2x CPU cores)
- High: Query result caching for frequent queries
- Medium: Tomcat connector thread tuning
- Expected: 60-70% response time improvement
📄 Page Rendering
- Critical: Template caching enabled
- Critical: Query caching with appropriate timespan
- High: Redis/Memcached for object caching
- High: G1GC for consistent response times
- Medium: CDN for static assets
- Expected: 70-85% response time improvement
⚙️ Batch Processing
- Critical: Async processing with thread pools
- Critical: Large heap (16GB+) with G1GC
- High: Batch size optimization (1000-5000 records)
- High: Database connection pooling
- Medium: Parallel processing where possible
- Expected: 50-65% processing time reduction
