**Describe the bug**
I have a module that is about 1k LOC, and its compilation time is about 30 sec. I started removing some parts of the code and seems like compilation time is reduced ~linearly with the amount of code I delete.

**To Reproduce**
This file is smaller and takes about 5 sec to compile.
https://github.com/fuelen/seed_factory/blob/main/test/support/schema_example.exs
```sh
$ git clone https://github.com/fuelen/seed_factory
$ echo -e "erlang 26.2.3\nelixir 1.16.2-otp-26" > .tool-versions
$ mise install
$ mix deps.get
$ mix compile
$ cp test/support/schema_example.exs lib/schema_example.ex
$ time mix compile
Compiling 1 file (.ex)
Generated seed_factory app
mix compile  7,21s user 1,49s system 190% cpu 4,563 total

```

**Expected behavior**
Faster compilation

**Runtime**
```
# .tool-versions
erlang 26.2.3
elixir 1.16.2-otp-26
```

 - OS: Arch Linux
 - Spark version: 1.1.55, but 2.1.18 is not faster
