📄 14% (0.14x) speedup for
JiraDataSource.set_dashboard_item_propertyinbackend/python/app/sources/external/jira/jira.py⏱️ Runtime :
2.26 milliseconds→1.98 milliseconds(best of229runs)📝 Explanation and details
The optimized code achieves a 14% runtime improvement through several key dictionary processing optimizations in the
set_dashboard_item_propertymethod:Primary Optimization - Smart Dictionary Conversion:
The original code called
_as_str_dict()three times duringHTTPRequestconstruction, spending ~52.6% of total time on these conversions. The optimization introduces_as_str_dict_cached()which:_AS_EMPTY_DICT_STRconstant instead of creating new empty dictsHeader Processing Optimization:
Replaces
dict(headers or {})+setdefault()pattern with conditional logic that avoids unnecessary dictionary operations when headers are empty or already contain 'Content-Type'.HTTP Client Merge Logic:
In
HTTPClient.execute(), the header merging logic now has fast-paths for empty dictionaries, avoiding the{**dict1, **dict2}spread operation when one dictionary is empty.Performance Impact:
_as_str_dictcalls dropped from 3.37ms total time to being replaced by much faster_as_str_dict_cachedcallsHTTPRequestconstruction time reduced significantly due to pre-computed string dictionariesTest Case Performance:
The optimizations are particularly effective for:
Trade-off Note:
While runtime improved 14%, throughput slightly decreased (-8.4%) due to the overhead of additional type checking in high-concurrency scenarios. This suggests the optimization favors latency over pure throughput, making it ideal for applications prioritizing response time over maximum request rate.
