The next performance improvements

Node.js

• Use fs.scandir from https://github.com/nodejs/node/issues/15699. Most likely it will give double performance increase for work with FS (not on all platforms). Right now I can use the scandir-native package, but this is native module and it requires compilation.

Algorithm

• Reduce search time for «constant» patterns (#60).

Code

• Write your own package for recursive directory reading. The readdir-enhanced is poorly maintained (code, architecture).

Unfortunately, built-in fs.readdir is low level solution. I can write my own solution (and I’ll do this as mentioned above), but this will still lead to additional code. We need to be able to understand whether this directory should be read or not (!**/node_modules), whether these entries should be filtered or not and etc.
