For certain newer compilers, this interpreter provides significantly better performance. Preliminary numbers on our machines suggest anywhere from -3% to 30% faster Python code, and a geometric mean of 9-15% -faster on ``pyperformance`` depending on platform and architecture. +faster on ``pyperformance`` depending on platform and architecture. The +baseline is Python 3.14 built with Clang 19 without this new interpreter. This interpreter currently only works with Clang 19 and newer on x86-64 and AArch64 architectures.
