v1.2.5

What's New in v1.2.5

🚀 Major Performance Improvements

Zero-Allocation Terminal Writer

• Completely redesigned TerminalWriter with zero allocations during operation
• Performance improvements:
  • Simple messages: 2x faster (203ns → 101ns)
  • With fields: 4.1x faster (703ns → 171ns)
  • Processes 7-8 million logs/second

✨ Key Changes

1. Pre-allocated Buffers

   • Increased buffer size from 1KB to 2KB to handle complex logs without reallocation
   • Reuses buffers across writes with mutex protection

2. Optimized String Operations

   • Direct byte slice operations instead of string conversions
   • Stack-based number formatting
   • Inline field decoding

3. Pre-computed Lookup Tables

   • Level strings and colors are pre-allocated
   • Padding spaces pre-allocated
