From f3ba814f6717263069bc113cea9dcab59bea5331 Mon Sep 17 00:00:00 2001 From: "codeflash-ai[bot]" <148906541+codeflash-ai[bot]@users.noreply.github.com> Date: Wed, 29 Oct 2025 12:48:25 +0000 Subject: [PATCH] Optimize construct_model_type_cache_path The optimized version achieves a **32% speedup** by eliminating redundant `os.path.join()` calls and intermediate variable creation. **Key optimization**: Instead of creating an intermediate `cache_dir` variable and making two separate `os.path.join()` calls, the optimized code performs a single `os.path.join()` call with all path components at once. **Original approach**: 1. Creates `cache_dir` with `os.path.join(MODEL_CACHE_DIR, dataset_id, version_id or "")` 2. Makes second `os.path.join(cache_dir, "model_type.json")` call **Optimized approach**: 1. Directly calls `os.path.join()` once with all components: `(MODEL_CACHE_DIR, dataset_id, version_id, "model_type.json")` 2. Uses conditional logic to handle the `None` version_id case cleanly **Why this is faster**: - Reduces function call overhead (1 vs 2 `os.path.join()` calls) - Eliminates intermediate string object creation (`cache_dir`) - Reduces memory allocations and string concatenations **Test performance**: The optimization shows consistent 25-55% improvements across all test cases, with particularly strong gains when `version_id` is `None` or empty (up to 54% faster). Large-scale tests with 100-1000 iterations show 28-48% speedups, demonstrating the optimization scales well with volume. --- inference/core/registries/roboflow.py | 9 +++++---- 1 file changed, 5 insertions(+), 4 deletions(-) diff --git a/inference/core/registries/roboflow.py b/inference/core/registries/roboflow.py index fddb1c0099..04e875b856 100644 --- a/inference/core/registries/roboflow.py +++ b/inference/core/registries/roboflow.py @@ -335,7 +335,8 @@ def _save_model_metadata_in_cache( def construct_model_type_cache_path( dataset_id: Union[DatasetID, ModelID], version_id: Optional[VersionID] ) -> str: - cache_dir = os.path.join( - MODEL_CACHE_DIR, dataset_id, version_id if version_id else "" - ) - return os.path.join(cache_dir, "model_type.json") + # Combine all path parts at once for efficiency + if version_id: + return os.path.join(MODEL_CACHE_DIR, dataset_id, version_id, "model_type.json") + else: + return os.path.join(MODEL_CACHE_DIR, dataset_id, "model_type.json")
