Expected behavior

should be faster, my ideal speed is to <= 50ms

Actual behavior

170ms ~ 200ms, however the prettier format can control under 50~100ms

Because I add it to codeActions, I can see a big delay after I cmd + s:

{
    "editor.codeActionsOnSave": {
        "source.addMissingImports": true,
        "source.fixAll.eslint": true,
        "source.fixAll.stylelint": true,
        "source.fixAll.markdownlint": true,
        "source.organizeImports.sortImports": true
    },
}

I try to analyze why slow from extension log:

1. format-imports seems try to get eslint rules info? I tiink it would be better to provide option instead of get eslint info. Like prettier, prettier hope user close all rules that should be handled by prettier.
2. After Finish format, why resolve config again?
