📄 77% (0.77x) speedup for CodeFlashBenchmarkPlugin.pytest_collection_modifyitems in codeflash/benchmarking/plugin/plugin.py

⏱️ Runtime : 271 microseconds → 153 microseconds (best of 1341 runs)

📝 Explanation and details

To optimize the provided Python code for better performance, we can reduce redundant checks and improve the loop efficiency. Here's an optimized version that maintains the same functionality while potentially running faster.

Summary of Changes.

1. Reduced redundant checks: Combined the fixturenames and marker checks into fewer lines and skipped the iteration as soon as the benchmark fixture or marker is found.
2. Improved readability and clarity: The logic is more straightforward, reducing complexity and the number of inspections on each loop iteration, potentially improving runtime performance.
