📄 8% (0.08x) speedup for
JiraDataSource.get_comment_property_keysinbackend/python/app/sources/external/jira/jira.py⏱️ Runtime :
2.87 milliseconds→2.66 milliseconds(best of194runs)📝 Explanation and details
The optimized code achieves an 8% runtime improvement and 1.0% throughput improvement through several targeted micro-optimizations that reduce memory allocations and eliminate unnecessary operations:
Key Optimizations:
Conditional Headers Assignment: Replaced
dict(headers or {})withheaders if headers is not None else {}, avoiding thedict()constructor call when headers are provided. This saves ~85ms in line profiler results.Eliminated Empty Dictionary Variables: Removed the allocation of
_query: Dict[str, Any] = {}and_body = Nonevariables, directly using{}andNonein the HTTPRequest constructor. This reduces memory allocations for frequently unused variables.Streamlined URL Construction: Removed the f-string wrapper
f"{request.url.format(**request.path_params)}"in HTTPClient.execute, using direct string formatting instead.Conditional Content-Type Check: Moved the content-type extraction inside the
isinstance(body, dict)check, avoiding the string operation when body is not a dictionary.Performance Impact:
The line profiler shows the most significant gains in
_as_str_dictcalls (reduced from 2.66ms to 2.21ms total time) and eliminated one_as_str_dictcall entirely for the empty query params. Thedict()constructor elimination in headers processing provides consistent per-call savings.Test Case Benefits:
The optimizations particularly benefit high-throughput scenarios (100+ concurrent requests) and sustained execution patterns where the per-call savings accumulate. Edge cases with None headers see the most dramatic improvement, while basic usage scenarios benefit from the reduced allocations across all dictionary operations.
These micro-optimizations are especially valuable for API client code that's likely called frequently in data processing pipelines, where even small per-call improvements compound significantly at scale.
