 ## ⚙️ Benchmarks
 
-The difference in sample size is due to the fact that fd and glob are different tools and have different use cases. fd is a command line tool that searches for files and directories. glob is a library that can be used to search for files and directories. The benchmark is done on a MacBook Air M2, 16 GB Unified memory.
