App goes very slow when "filereplacements" implementing in angular.json in angular ionic app

Question

When I change the environments configuration in angular.json,

"customer1-dev": {
            "fileReplacements": [
                {
                    "replace": "src/environments/environment.ts",
                    "with": "src/environments/environment.customer1.ts"
                }
            ],
            "buildOptimizer": false,
            "optimization": false,
            "vendorChunk": true,
            "extractLicenses": false,
            "sourceMap": true,
            "namedChunks": true
            
        },

When I add 'fileReplacements' in the configuration, my app run very slow.

and when I remove the 'fileReplacements' then app run faster.

I had create a environment setup for the different-2 customer with the same app source-code. Reference URL That's why I need to setup configuration in angular.json.

Environment setup for customer specific, is working fine but app run very slow.

can you include all of the configurations inside angular.json? if you're trying to run production settings e.g. optimization: true during development it will be slow. A development config may be helpful — Andrew Allen

Typical development config:

{
    "configurations": {
        ...
        // can change "development" to any configuration target
        "development": {
          "buildOptimizer": false,
          "optimization": false,
          "vendorChunk": true,
          "extractLicenses": false,
          "sourceMap": true,
          "namedChunks": true,
          "fileReplacements": [...]
        }
}

By not optimising the dev server is faster. Obviously you'll need a separate production config to get an optimised build.

Yes, I also try this but still run very slow.

Yeah, just saw update to your post. Not sure. As far as I know fileReplacements runs only once so the app being slow doesn't make sense
