The optimization achieves an 11% speedup by eliminating function call overhead and using more efficient string concatenation:
Key Optimizations:
Function Call Elimination: Inlined the
get_vertex_base_url()
logic directly intoget_default_base_target_url()
, removing the overhead of 2,046 function calls. Each call had ~2.9μs overhead based on the profiler data.String Concatenation Method: Replaced f-string formatting with direct string concatenation (
"https://" + str(vertex_location) + "-aiplatform.googleapis.com/"
). For simple concatenations like this, the+
operator is faster than f-string interpolation in Python.Explicit Type Conversion: Added
str(vertex_location)
to handle non-string inputs consistently, which the f-string was doing implicitly but less efficiently.Performance Characteristics:
str()
conversion overhead, but this is offset by eliminating function call overhead in real usage patterns.The optimization trades slightly slower individual non-global calls for much faster global calls and eliminates consistent function call overhead across all invocations.
