📄 33% (0.33x) speedup for get_annual_indicator_names in qnt/data/secgov_fundamental.py

⏱️ Runtime : 693 microseconds 522 microseconds (best of 173 runs)

📝 Explanation and details

The optimized code achieves a 32% speedup by converting the membership testing from O(N*M) to O(1) lookups and using more efficient set operations.

Key optimizations:

  1. Set conversion for O(1) lookups: Converts GLOBAL_ANNUAL_US_GAAPS (a list) to a set once at the beginning. This changes each fact in GLOBAL_ANNUAL_US_GAAPS lookup from O(M) list scanning to O(1) hash table lookup, where M is the size of the GAAP list (~23 elements).

  2. Set subset operation: Replaces the generator expression all(fact in GLOBAL_ANNUAL_US_GAAPS for fact in facts) with set(facts).issubset(global_annual_us_gaaps_set). This leverages optimized C-level set operations instead of Python loops.

  3. Empty facts handling: Explicitly handles the edge case where facts is empty to preserve the original logic (empty facts should be included, as all() on empty iterables returns True).

Why this works:
The original code performed ~69% of its time (2.02ms out of 2.94ms total) on the membership checking line. With 1,240 indicators tested and potentially multiple facts per indicator, the O(N*M) complexity of repeated list lookups became the bottleneck. Set operations are implemented in C and highly optimized for these exact use cases.

Test case performance:
The optimization shows consistent 15-45% improvements across all test scenarios, with the largest gains (35-45%) occurring in edge cases with empty facts or when the GAAPS list is cleared, suggesting the set conversion overhead is minimal compared to the lookup savings.

The optimized code achieves a **32% speedup** by converting the membership testing from O(N*M) to O(1) lookups and using more efficient set operations.

**Key optimizations:**

1. **Set conversion for O(1) lookups**: Converts `GLOBAL_ANNUAL_US_GAAPS` (a list) to a set once at the beginning. This changes each `fact in GLOBAL_ANNUAL_US_GAAPS` lookup from O(M) list scanning to O(1) hash table lookup, where M is the size of the GAAP list (~23 elements).

2. **Set subset operation**: Replaces the generator expression `all(fact in GLOBAL_ANNUAL_US_GAAPS for fact in facts)` with `set(facts).issubset(global_annual_us_gaaps_set)`. This leverages optimized C-level set operations instead of Python loops.

3. **Empty facts handling**: Explicitly handles the edge case where `facts` is empty to preserve the original logic (empty facts should be included, as `all()` on empty iterables returns `True`).

**Why this works:**
The original code performed ~69% of its time (2.02ms out of 2.94ms total) on the membership checking line. With 1,240 indicators tested and potentially multiple facts per indicator, the O(N*M) complexity of repeated list lookups became the bottleneck. Set operations are implemented in C and highly optimized for these exact use cases.

**Test case performance:**
The optimization shows consistent 15-45% improvements across all test scenarios, with the largest gains (35-45%) occurring in edge cases with empty facts or when the GAAPS list is cleared, suggesting the set conversion overhead is minimal compared to the lookup savings.
