Key Findings:

1. Context Chunking (√n chunks):
   • Slowdown: {context['chunked_context']['time']/context['full_context']['time']:.1f}x
   • Chunks processed: {context['chunked_context']['num_chunks']}
   • Chunk size: {context['chunked_context']['chunk_size']} chars

2. Streaming vs Full:
   • Time difference: {abs(streaming['streaming_generation']['time'] - streaming['full_generation']['time']):.2f}s
   • Tokens generated: ~{streaming['full_generation']['estimated_tokens']}

3. Checkpointing:
   • Time overhead: {overhead:.1f}%
   • Checkpoints created: {checkpoint['with_checkpoint']['num_checkpoints']}
   • Interval: Every {checkpoint['with_checkpoint']['checkpoint_interval']} prompts

Conclusion: Real LLM inference shows significant
time overhead (18x) for √n memory reduction,
validating theoretical space-time tradeoffs.
