Fix decorator-related slow performance #2095

Open bzczb opened 5 months ago

bzczb commented 5 months ago

Inside decorators preprocess_args() and use_clip_fps_by_default(), capture the inspected argnames at decoration time instead of recomputing them every time the wrapped function is called. This improves performance by a great deal, particularly when rendering audio.

Fixes #2094 Certain decorators perform extremely slow function inspection every call
