📄 7% (0.07x) speedup for AsyncRawRequestsClient.get in src/deepgram/manage/v1/projects/requests/raw_client.py

⏱️ Runtime : 15.4 milliseconds 14.5 milliseconds (best of 79 runs)

📝 Explanation and details

The optimized code achieves a 6% runtime speedup and 1.3% throughput improvement through two key optimizations:

1. Fast-path optimization in jsonable_encoder:

  • Moved the most common type checks (str, int, float, None) to the very beginning of the function, before any other processing
  • This eliminates unnecessary work for simple types that comprise the majority of encoding operations
  • Line profiler shows the fast-path now handles 880 hits in just 0.49ms vs 3.12ms in the original, a 84% reduction in encoding time

2. Streamlined header and parameter processing in AsyncHttpClient.request:

  • Replaced nested dictionary merging with flattened sequential updates using .update()
  • Eliminated redundant isinstance checks and temporary variable creation
  • Simplified conditional logic for file processing and parameter filtering
  • Combined multiple dictionary operations into single passes

Why these optimizations work:

  • Type checking order matters: In JSON encoding, primitive types (strings, numbers) are far more common than complex objects. Moving these checks first eliminates expensive isinstance calls for Pydantic models and dataclasses on simple data.
  • Dictionary operations are costly: The original code created multiple intermediate dictionaries and performed redundant merging operations. The optimized version uses in-place updates and avoids unnecessary allocations.

Test case performance:
The optimizations are particularly effective for the test cases involving high-volume concurrent requests (test_get_throughput_high_volume with 100 concurrent requests), where the reduced per-operation overhead compounds significantly across many calls. The encoding improvements benefit all test cases since every HTTP request involves JSON encoding of headers and parameters.
