Tar / Tar fs Benchmark

1results.md

Times are off of my Linux laptop.

You can run with: ```console $ npx https://gist.github.com/acfba145e421d51c4de2cdb7faa3f309.git

With default config, using node_modules, which has 1295 files (6.6M):

```console
$ node benchmark.js
Overall Benchmarking...
        tar x 
        6.92ops/sec ±3.86% (83 runs sampled)
        tar-fs x 3.44 ops/sec ±4.76% (51 runs sampled)
Overall Successful:
        tar, tar-fs
Overall Fastest:
        tar

With my downloads folder, with 505 directories and 59,511 files (5.6G):

$ node benchmark.js
Overall Benchmarking...
        tar x 0.09 ops/sec ±1.83% (5 runs sampled)
        tar-fs x 0.05 ops/sec ±2.30% (4 runs sampled)
Overall Successful:

Overall Fastest:
        tar
