Multithreaded copy tool implement by rust. Focus primarily on a large number of small files.
You need to install the rust compiler toolchain first.
Run cargo build --release to compile.
Then you can add target\release\r-fast-copy[.exe] to your path.
Run cargo run -- -h or r-fast-copy -h to get usage.
r-fast-Copy also provides a subcommand for generating test folder at a given location.
Run cargo run -- gen-test-folder -h or r-fast-copy gen-test-foler -h to get usage.
The benchmark generated by copying same folder 3 times with different thread counts.
