I just ran cabal init, and then did emacs . and it took around 4 seconds.

This is a fun game.

Did you use Eglot(LSP client) ?
It takes HLS this much time

That is odd. What happens if you run haskell-language-server on the command line, or cabal build?

5

I think this issue only occurs when I open the project for the first time

6

Is it reproducible, i.e. does the same thing happen with every new project?

7

I think it’s likely due to cabal needs to build all the dependencies. Perhaps try to build the project and wait it finish, before opening in the IDE?

But how come building a few libs take more than 2 mins ?? Is Cabal slow ??
