| 100% Rust |
| Powered by the Rayon library for high parallel perfomance |
| Supported on Unix-based platforms or Windows |
| Extremely fast at synchronizing directories with large quantities of files |
| Multithreaded copy, remove, and sync |
| A progress bar using indicatif |

<TARGET> Target directoryUsing hyperfine on an Intel i7-8550U with the following 2 test folders,
| Directory | Directory Size | Number of Files |
|---|---|---|
| 1 | 88MB | 7262 |
| 2 | 105MB | 252 |
| Command | Directory | Time |
|---|---|---|
| lms sync | 1 | 179.1 ms ± 5.1 ms |
| rsync -r --delete | 1 | 717.8 ms ± 41.1 ms |
| lms cp | 1 | 117.3 ms ± 3.6 ms |
| cp -r | 1 | 283.4 ms ± 13.2 ms |
| lms rm | 1 | 147.6 ms ± 8.6 ms |

Of course, these benchmarks can be highly dependent on CPU and IO devices.
