Code Review: Performance Analysis Script

Overall, this is a well-structured utility script for analyzing llama.cpp server logs. The code is clean, uses good Python practices (dataclasses, enums, type hints), and includes comprehensive documentation.

🟢 Strengths

• Clean architecture: Good use of @dataclass, Enum, and type hints throughout
• Error handling: Proper file validation and OSError handling in main()
• Modular design: Extraction, plotting, and CLI parsing are well-separated
• Documentation: README.md is clear with usage examples

🟡 Suggestions

1. Type hint issue (perf_analysis.py:166):

   def autopct_with_seconds(values: Sequence[float]) -> callable:

   Should be Callable[[float], str] (capitalized, from typing). callable is a builtin function, not a type.

2. Potential division by zero (perf_analysis.py:305-309):
   The if tps > 0 guard is good, but consider logging/warning when TPS values are zero since it indicates missing data.

3. Output directory flexibility: Currently saves to current working directory. Consider adding an --output-dir argument for flexibility.

4. Missing file header year range (perf_analysis.py:3):

   # Copyright(C) 2025-2026 Advanced Micro Devices, Inc.

   Per CLAUDE.md, should be 2024-2025. The 2025-2026 range seems incorrect.

5. Unused import (perf_analysis.py:22):
   Tuple from typing is imported but Python 3.9+ allows using tuple directly in annotations (already used in some places).

6. Consider adding --quiet flag: The script prints status messages for each plot. A quiet mode would be useful for scripted usage.

🟢 Minor Nits

• README.md line 44 has a trailing newline (cosmetic)
• Consider adding example output screenshots to the README for users unfamiliar with the metrics

Summary

This is solid, production-ready code. The suggestions above are minor improvements. The script will be valuable for profiling GAIA agent performance with Lemonade.

Recommendation: Approve with minor fixes for the copyright year and type hint.

@claude I fixed the typing issues. I will address the header issue in another PR. Anything else for this one?

Review: Updated Code

I see the type hint fix on line 166 - you've updated from callable to Callable[[float], str]. However, there's a missing import that will cause a runtime error:

🔴 Issue: Missing Import (perf_analysis.py:22,166)

# Line 22 - Current:
from typing import Dict, Iterable, List, Sequence, Tuple

# Line 166 uses:
def autopct_with_seconds(values: Sequence[float]) -> Callable[[float], str]:

Callable is used but not imported. This will raise a NameError when the function is called.

Fix: Add Callable to the import:

from typing import Callable, Dict, Iterable, List, Sequence, Tuple

Also, as noted before, Tuple is imported but unused since you're using tuple directly in type hints (Python 3.9+ style). You could remove it, but it's not critical.

Summary

One quick fix needed - add Callable to the imports on line 22. Everything else looks good!

@claude good catch! Fixed that. Anything else?

Final Review Check

• Read the updated perf_analysis.py file
• Verify the Callable import fix
• Check for any remaining issues
• Provide final feedback

Review Complete

The Callable import is now correctly added on line 22. The code looks good to go!

One tiny remaining nit:

• 🟢 Minor: Tuple was removed from the import (good!) but you're using Tuple on line 117 in the type hint Sequence[Tuple[str, List[float]]]. This will cause a NameError at runtime. Either:
  • Add Tuple back to the imports, or
  • Use lowercase tuple (Python 3.9+ style): Sequence[tuple[str, List[float]]]

Same applies to lines 150, 272, and 275.

Otherwise, this PR is ready to merge!
