📄 44% (0.44x) speedup for JiraDataSource.get_dashboard in backend/python/app/sources/external/jira/jira.py

⏱️ Runtime : 3.53 milliseconds 2.46 milliseconds (best of 221 runs)

📝 Explanation and details

The optimized code achieves a 43% runtime improvement and 17.6% throughput increase through three key optimizations that eliminate unnecessary overhead in the hot path of get_dashboard:

1. Eliminated Complex URL Formatting

  • Original: Used _safe_format_url(rel_path, _path) which calls template.format_map(_SafeDict(params)) and includes exception handling
  • Optimized: Direct string replacement with rel_path.replace('{id}', str(id))
  • Impact: Line profiler shows URL construction dropped from 19.6% to 4.9% of total time - a ~75% reduction in this operation

2. Avoided Unnecessary Dictionary Construction

  • Original: Always called dict(headers or {}) which creates a new dictionary even when headers is None
  • Optimized: Uses conditional assignment headers if headers is not None else {} to avoid allocation when headers is None
  • Impact: Reduced memory allocation overhead, particularly beneficial in concurrent scenarios

3. Inlined Dictionary Conversions for Known Small Collections

  • Original: Called _as_str_dict() for _path (always 1 item) and _query (always empty)
  • Optimized: Directly constructs the small dictionaries inline: {'id': _serialize_value(id)} and {}
  • Impact: Line profiler shows path_params conversion time dropped from 20% to 14.5% of total execution

Performance Benefits by Test Type:

  • Basic operations: All basic tests benefit from reduced per-call overhead
  • Concurrent workloads: The 50-200 concurrent test cases see amplified benefits since each call is faster
  • Edge cases: String handling optimizations are particularly effective for special characters and long IDs

The optimizations are most effective in high-throughput scenarios where get_dashboard is called frequently, as they eliminate function call overhead and unnecessary object allocations in the critical path. The HTTP client header merging optimization in the second file further reduces dictionary operations when request headers are present.
