📄 44% (0.44x) speedup for
JiraDataSource.get_dashboardinbackend/python/app/sources/external/jira/jira.py⏱️ Runtime :
3.53 milliseconds→2.46 milliseconds(best of221runs)📝 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
_safe_format_url(rel_path, _path)which callstemplate.format_map(_SafeDict(params))and includes exception handlingrel_path.replace('{id}', str(id))2. Avoided Unnecessary Dictionary Construction
dict(headers or {})which creates a new dictionary even when headers is Noneheaders if headers is not None else {}to avoid allocation when headers is None3. Inlined Dictionary Conversions for Known Small Collections
_as_str_dict()for_path(always 1 item) and_query(always empty){'id': _serialize_value(id)}and{}Performance Benefits by Test Type:
The optimizations are most effective in high-throughput scenarios where
get_dashboardis 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.✅ Correctness verification report:
