OpenDAL Benchmark VS Fs

This benchmark compares the performance of OpenDAL with the performance of the std::fs.

Goal

We expect OpenDAL to match std::fs in speed: the throughput of OpenDAL should be within a 5% range of std::fs.

Usage

For test: cargo run

Testing vs_fs/std_fs_read
Success
Testing vs_fs/opendal_fs_read
Success
Testing vs_fs/opendal_fs_read_with_range
Success

For bench: cargo run --release -- --bench
