Performance Optimization in TuskLang - Bash Guide

⚡ Revolutionary Performance Configuration

Performance optimization in TuskLang transforms your configuration files into intelligent performance systems. No more separate optimization frameworks or complex performance tuning - everything lives in your TuskLang configuration with dynamic optimization strategies, automatic performance monitoring, and intelligent resource management.

> "We don't bow to any king" - TuskLang performance optimization breaks free from traditional performance constraints and brings modern optimization capabilities to your Bash applications.

🚀 Core Performance Directives

Basic Performance Setup

#performance: enabled              # Enable performance optimization
#perf-enabled: true               # Alternative syntax
#perf-monitoring: true            # Enable performance monitoring
#perf-profiling: true             # Enable performance profiling
#perf-caching: true               # Enable performance caching
#perf-compression: gzip           # Enable compression

Advanced Performance Configuration

#perf-memory-limit: 1GB           # Memory usage limit
#perf-cpu-limit: 80%              # CPU usage limit
#perf-disk-limit: 90%             # Disk usage limit
#perf-network-limit: 100MB/s      # Network bandwidth limit
#perf-thread-pool: 10             # Thread pool size
#perf-connection-pool: 20         # Connection pool size
