Go Performance Optimization Guide

🚀 Key Strategies for Efficient Go Code

• Optimize Allocations: Use sync.Pool for reusing objects and reduce GC pressure
• Leverage Built-in Tools:
  • Use pprof for CPU/memory profiling
  • Enable gc flags for advanced garbage collection tuning
  
• Reduce Lock Contention:
  • Use read-write mutexes (sync.RWMutex)
  • Implement lock-free patterns where possible
  
• Optimize Data Structures:
  • Prefer slice over array for dynamic sizing
  • Use map[string]struct{} for fast lookups
  

🔍 Advanced Optimization Techniques

• Use unsafe Package Sparingly:
  • For pointer manipulation and memory optimizations
  • Be cautious with memory safety
  
• Enable Compiler Optimizations:
  • Use -gcflags="-m" to analyze memory allocation
  • Compile with -race for detecting data races
  
• Optimize I/O Operations:
  • Use buffered I/O (bufio)
  • Implement connection pooling for databases
