perf improvements

just had a test on a private repo:

react/jsx-indent                  |    84.047 |     0.6%
import/export                     |    72.087 |     0.5%
@typescript-eslint/no-unused-vars |    71.559 |     0.5%

seems some of the rules in the plugin cost too much time, any ideas to improve it? just bring it up as I didn't find any discussion about it. :)
