Generation is taking >4 minutes for a schema with 400 models

[cb-vigneshsm]

Describe the Bug
Generator typegraphql-prisma is taking >4 minutes compared to prisma client for a schema with >400 models while prisma client takes just under 1-2 seconds. Is this expected behaviour ?

To Reproduce
Run npx prisma generate on a schema with lot of models with below generator

generator typegraphql {
  provider           = "typegraphql-prisma"
  useOriginalMapping = "true"
}

Expected Behavior
I would expect it to be taking just a few seconds to generate everything.

Try not to emit to node_modules but emit source code files, so it will be faster thanks to not compiling the TS code.

I have set the output directory to outside node_modules, but does not seem to help
