📄 75% (0.75x) speedup for
CohereChatConfig.map_openai_paramsinlitellm/llms/cohere/chat/transformation.py⏱️ Runtime :
198 microseconds→113 microseconds(best of329runs)📝 Explanation and details
The optimization replaces sequential
ifstatement chains with a single dictionary lookup, dramatically reducing computational overhead in themap_openai_paramsmethod.Key Changes:
if param == "..."checks for each parameter, the code now uses aparam_mapdictionary and performs a singleif param in param_mapcheck followed by direct lookup.Why This Is Faster:
in param_map) is O(1) average case, while sequential string comparisons are O(n) where n is the number of supported parameters.Performance Characteristics:
The optimization excels with larger parameter sets - showing 309% speedup in the
test_large_scale_many_paramscase with 900+ parameters, where the original code's linear scanning becomes expensive. For small parameter sets (1-2 params), there's a slight overhead from dictionary creation, but this is negligible compared to the gains on realistic workloads with multiple OpenAI parameters being mapped.✅ Correctness verification report:
