📄 34% (0.34x) speedup for
_encode_trace_idinchromadb/telemetry/opentelemetry/grpc.py⏱️ Runtime :
1.30 milliseconds→967 microseconds(best of206runs)📝 Explanation and details
The optimization replaces the two-step process of
binascii.hexlify().decode()with the nativebytes.hex()method.Key Change:
binascii.hexlify(trace_id.to_bytes(16, "big")).decode()trace_id.to_bytes(16, "big").hex()Why it's faster:
binascii.hexlify()and then.decode()bytes.hex()is implemented directly in C within the Python interpreter, avoiding Python function call overheadPerformance benefits:
The line profiler shows a 25% reduction in per-hit time (518.9ns → 390ns), and the annotated tests demonstrate consistent 30-60% speedup across all test cases. The optimization is particularly effective for:
This is a classic example of leveraging built-in Python methods over library functions for better performance in hot code paths.
