⚡️ Speed up method UsersGroupsDataSource.users_user_get_managed_app_diagnostic_statuses by 105%

[codeflash-ai]

📄 105% (1.05x) speedup for UsersGroupsDataSource.users_user_get_managed_app_diagnostic_statuses in backend/python/app/sources/external/microsoft/users_groups/users_groups.py

⏱️ Runtime : 693 microseconds → 339 microseconds (best of 7 runs)

📝 Explanation and details

The optimized code achieves a 104% speedup (runtime reduced from 693 to 339 microseconds) by eliminating redundant conditional checks and property assignments through more efficient object initialization patterns.

Key Optimizations Applied:

1. Consolidated Object Construction: Instead of creating empty UsersRequestBuilderGetQueryParameters() and then conditionally setting properties via multiple if statements, the optimized version constructs the object directly with all parameters in a single call, reducing method invocation overhead.

2. Eliminated Redundant Conditionals: The original code performed 7 separate conditional checks (if select:, if expand:, etc.) followed by property assignments. The optimization moves the conditional logic into the constructor call using ternary expressions, reducing the total number of operations from ~15 to ~7.

3. Streamlined Header Handling: Uses dictionary unpacking {**(headers or {})} during config construction instead of conditional assignment afterward, eliminating a separate if headers: check and property assignment.

Performance Impact by Test Case:

• Basic operations (single user queries): Benefit most from reduced overhead in query parameter construction
• Concurrent execution (5-50 simultaneous calls): Each call experiences the same per-operation speedup, resulting in better overall throughput under load
• Parameter-heavy calls (with select, expand, filters): See the greatest benefit since these trigger the most conditional checks in the original code

The line profiler shows the optimization primarily reduces time spent in query parameter setup (lines that previously took 10.4% of execution time), allowing more time for the actual API call execution.
