📄 6% (0.06x) speedup for
GraphicsContextPdf.fillinlib/matplotlib/backends/backend_pdf.py⏱️ Runtime :
590 microseconds→555 microseconds(best of61runs)📝 Explanation and details
The optimization replaces
if len(args):withif args:in the condition check. This change provides a 6% speedup by eliminating the overhead of calling thelen()function.Key optimization:
if len(args):toif args:if args:) is faster than computing its length (if len(args):). Thelen()function call adds unnecessary overhead when we only need to know if the collection is non-empty.How it works:
argscontains elementsif args:directly checks if the tuple is truthy (non-empty), which is a simple pointer/size checkif len(args):requires a function call to compute the length, then checks if that result is truthyTest case analysis:
The optimization shows consistent improvements across most test scenarios:
This is a micro-optimization that provides measurable benefits in a graphics context where the
fill()method is likely called frequently during rendering operations.✅ Correctness verification report:
