📄 11% (0.11x) speedup for OneNoteDataSource.groups_group_onenote_notebooks_notebook_section_groups_section_group_sections_onenote_section_copy_to_notebook in backend/python/app/sources/external/microsoft/one_note/one_note.py

⏱️ Runtime : 1.37 milliseconds 1.24 milliseconds (best of 73 runs)

📝 Explanation and details

The optimized code achieves a 10% runtime improvement (1.37ms → 1.24ms) and 1.4% throughput increase through three key optimizations:

1. Eliminated Unnecessary Object Instantiation

  • Replaced RequestConfiguration() object creation for query parameters with a simple dictionary (query_params = {}), only creating the RequestConfiguration object when actually needed
  • Line profiler shows the original instantiation took 728,289ns (10.8% of execution time), now reduced to 154,415ns (2.3%)

2. Conditional Query Parameter Assignment

  • Added if query_params: check before assigning to config.query_parameters, avoiding unnecessary assignment when no query parameters are provided
  • This prevents creating empty query parameter objects for requests that don't need them

3. Optimized Method Chain Access

  • Split the long chained method call into a variable (section_req) to avoid redundant property lookups during the API call
  • The line profiler shows this reorganization improved performance by reducing repeated attribute access overhead

4. Input Protection Enhancement

  • Added headers.copy() to prevent mutation of the input headers dictionary, improving safety without performance cost

These optimizations are particularly effective for high-volume OneNote API operations, as evidenced by the throughput tests showing consistent improvements across small (10), medium (50), and large (100) concurrent request loads. The optimizations reduce object creation overhead and method resolution time, which compounds when processing many concurrent requests typical in OneNote integration scenarios.

The optimized code achieves a 10% runtime improvement (1.37ms → 1.24ms) and 1.4% throughput increase through three key optimizations:

**1. Eliminated Unnecessary Object Instantiation**
- Replaced `RequestConfiguration()` object creation for query parameters with a simple dictionary (`query_params = {}`), only creating the `RequestConfiguration` object when actually needed
- Line profiler shows the original instantiation took 728,289ns (10.8% of execution time), now reduced to 154,415ns (2.3%)

**2. Conditional Query Parameter Assignment**
- Added `if query_params:` check before assigning to `config.query_parameters`, avoiding unnecessary assignment when no query parameters are provided
- This prevents creating empty query parameter objects for requests that don't need them

**3. Optimized Method Chain Access**
- Split the long chained method call into a variable (`section_req`) to avoid redundant property lookups during the API call
- The line profiler shows this reorganization improved performance by reducing repeated attribute access overhead

**4. Input Protection Enhancement**
- Added `headers.copy()` to prevent mutation of the input headers dictionary, improving safety without performance cost

These optimizations are particularly effective for high-volume OneNote API operations, as evidenced by the throughput tests showing consistent improvements across small (10), medium (50), and large (100) concurrent request loads. The optimizations reduce object creation overhead and method resolution time, which compounds when processing many concurrent requests typical in OneNote integration scenarios.
