⚡️ Speed up method OnCallPagingApi.resolve_on_call_page by 5%

[codeflash-ai]

📄 5% (0.05x) speedup for OnCallPagingApi.resolve_on_call_page in src/datadog_api_client/v2/api/on_call_paging_api.py

⏱️ Runtime : 3.72 milliseconds → 3.53 milliseconds (best of 66 runs)

📝 Explanation and details

The optimized code achieves a 5% speedup through two key micro-optimizations that reduce function call overhead:

Key Optimizations:

1. Direct parameter passing in resolve_on_call_page: Eliminated the intermediate dictionary creation (kwargs: Dict[str, Any] = {} and kwargs["page_id"] = page_id) and passed the parameter directly as page_id=page_id. This removes two variable assignments and dictionary operations.

2. Import reorganization: Separated the ApiClient import from the Endpoint import to potentially reduce import resolution overhead, though this has minimal impact.

Why This Works:

• The line profiler shows that 95.4% of the original function's time was spent in call_with_http_info, but the remaining 4.6% was overhead from dictionary operations
• By eliminating the kwargs dictionary creation and assignment, we remove Python's dictionary allocation and key assignment operations
• Direct parameter passing is more efficient than **kwargs unpacking, especially for single parameters

Test Case Performance:
The optimizations show consistent improvements across different scenarios:

• Best performance gains (8-14% faster) occur with error cases and invalid inputs, where the reduced overhead is more noticeable relative to the shorter execution path
• Bulk operations see 7-8% improvements, demonstrating the optimization scales well with repeated calls
• Valid UUID operations see 5-10% improvements, matching the overall 5% speedup

This optimization is particularly effective for high-frequency API calls where every microsecond of overhead reduction compounds significantly.
