Micromatch performance

[mrmlnc]

We need fix performance for the micromatch package.

So, we spend about 30ms (for 400 entries with 50 depth) to find the regular expression for the pattern in the cache when we pass options. Proof:

• https://github.com/micromatch/micromatch/blob/master/lib/utils.js#L83-L94
• https://github.com/micromatch/micromatch/blob/master/lib/utils.js#L295-L309 (more time)

Before:

fast-glob-current.js
(TIME) 81.862ms ±2.573% | (MEMORY) 8.357MB ±0.081% | Entries: 200 | Errors: 0 | Retries: 1
fast-glob-previous.js
(TIME) 60.310ms ±1.405% | (MEMORY) 10.533MB ±0.073% | Entries: 200 | Errors: 0 | Retries: 1

After (Transform patterns to RegExps once in Reader class):

P.S: You need to look at the diff between numbers.
