Benchmarks

The following benchmarks show that DotNetGlob outperforms https://github.com/kthompson/glob/ when testing how fast it is as evaluating non-matching strings.

The following are the results from benchmarking the Glob.IsMatch() method, against a number of generated non-matching strings. The results are summarised by Glob Pattern, Number of generated strings tested against the glob, and the version of the runtime (benchmarks are run accross a range of runtimes).

The percentages represent the proportion of time it takes for DotNet.Glob to return a result, compared to the time it takes for https://github.com/kthompson/glob/ as the comparison. Therefore on average, DotNet.Glob takes 15.17% of the time it takes glob to match unsuccesful strings to the pattern p?th/a[bcd]b[e-g].txt. Other variations show DotNet.Glob also performs favourably:
